California Vehicle Code Section 21703 VC addresses a common but often misunderstood driving behavior—following another vehicle too closely, commonly referred to as tailgating. This statute exists to promote road safety and prevent rear-end collisions, which are among the most frequent types of traffic accidents. Understanding what constitutes a violation, the consequences, and how to avoid tailgating is essential for all California drivers.
What the Law Says
Under California Vehicle Code § 21703 VC, the law reads:
“The driver of a motor vehicle shall not follow another vehicle more closely than is reasonable and prudent, having due regard for the speed of such vehicle and the traffic upon, and the condition of, the roadway.”
This means drivers must keep a safe distance behind the vehicle in front of them, taking into account speed, traffic density, and road conditions. Unlike some traffic laws that specify fixed distances or time intervals, 21703 VC is based on what is considered “reasonable and prudent” under current conditions. This subjectivity allows law enforcement officers and courts to evaluate each situation individually.
Interpreting “Reasonable and Prudent”
The term “reasonable and prudent” gives law enforcement the discretion to determine whether a driver is following too closely. Factors that influence this judgment include:
-
The speed of both vehicles
-
The condition of the road (dry, wet, icy, etc.)
-
Weather and visibility
-
Traffic congestion
-
The size and type of vehicle (larger vehicles require more stopping distance)
There is no fixed rule in the statute, but drivers are generally encouraged to follow the “three-second rule” as a practical measure. This rule recommends staying at least three seconds behind the vehicle ahead under normal driving conditions. This time gap should be increased in adverse weather or when driving at high speeds.
Why Tailgating is Dangerous
21703 VC Tailgating significantly increases the risk of a rear-end collision. When drivers do not leave adequate space between vehicles, they reduce their reaction time and braking distance. If the vehicle in front suddenly stops or slows down, a tailgating driver may not have enough time to respond, often resulting in an accident.
In many cases, rear-end collisions caused by following too closely result in property damage and injury. Victims often suffer from whiplash, back injuries, or worse. Because of the frequency and severity of these incidents, California law treats tailgating as a serious traffic violation.
Penalties for Violating 21703 VC
A driver found to be in violation of Vehicle Code § 21703 VC may face the following penalties:
1. Monetary Fine
A violation of California Vehicle Code § 21703 typically results in a fine of $238 plus court costs.
2. Point on Driving Record
A violation adds one point to a driver’s record with the California Department of Motor Vehicles (DMV). Points on your record can accumulate over time and may result in license suspension under California’s Negligent Operator Treatment System if you accrue:
-
4 points in 12 months
-
6 points in 24 months
-
8 points in 36 months
3. Increased Insurance Premiums
Auto insurance companies frequently review driving records when determining rates. Even a single point from a 21703 VC violation can lead to a noticeable increase in premiums. In some cases, insurance providers may cancel or refuse to renew a policy for drivers with multiple violations.
Contesting a Tailgating Ticket
A driver who receives a citation for following too closely has the right to contest the ticket in traffic court. There are several potential defenses that can be used, including:
1. Reasonable Following Distance
The driver may argue that the following distance was safe and appropriate based on the conditions at the time. This could include evidence of low speeds, light traffic, or dry road conditions.
2. Unsafe Behavior by the Other Driver
If the vehicle in front made a sudden and unexpected stop, changed lanes without signaling, or cut into the lane abruptly, the accused driver may not be at fault.
3. Lack of Clear Observation
Because 21703 VC relies on an officer’s judgment, it may be possible to argue that the citation was based on limited or inaccurate visual observation, especially in heavy traffic.
In most cases, presenting a strong defense may require supporting evidence such as dashcam footage, witness testimony, or expert input on vehicle spacing and reaction times.
How to Avoid Tailgating
To prevent tailgating and reduce the risk of receiving a citation or being involved in an accident, drivers should follow these best practices:
1. Maintain Adequate Following Distance
Use the three-second rule as a baseline and increase your following distance in adverse weather or at high speeds. For example, increase to four or five seconds in heavy rain, fog, or on poorly maintained roads.
2. Stay Focused on the Road
Avoid distractions that may cause you to unintentionally close the gap with the vehicle in front. Texting, eating, or even adjusting the radio can affect your reaction time.
3. Drive Defensively
Anticipate sudden stops and changes in traffic patterns. Avoid aggressive maneuvers, and always give yourself enough space to react to unexpected developments.
4. Be Patient in Traffic
In congested conditions, leave extra space when possible and avoid the temptation to follow too closely out of frustration. It is better to arrive safely and legally than risk a collision or citation.
Dealing with Tailgaters
If another driver is following you too closely, the best course of action is to remain calm and avoid engaging in aggressive behavior. If possible, change lanes to allow the tailgater to pass. Do not brake suddenly or attempt to “punish” the other driver, as this could escalate the situation or cause an accident.
Tailgating in Commercial and Heavy Vehicles
Commercial drivers operating large trucks or buses have a greater responsibility to maintain safe following distances due to longer stopping distances. A tailgating violation involving a commercial vehicle may result in more severe consequences, including commercial license suspension or employer disciplinary action.
Tailgating and Rear-End Collisions
In most rear-end accidents, the driver who struck the vehicle in front is presumed to be at fault. If it is determined that the accident occurred because the rear driver was following too closely, liability may fall entirely on that driver. In civil cases, this can result in substantial financial damages for injuries, vehicle repairs, and lost wages.
Conclusion
California Vehicle Code § 21703 VC plays a vital role in ensuring road safety by discouraging unsafe driving behavior like tailgating. While it may seem like a minor infraction, following too closely can lead to serious legal consequences, traffic collisions, and financial liability. Every driver has a responsibility to maintain a safe following distance, remain alert, and practice defensive driving at all times.

Understanding California Vehicle Code § 21453 CVC: Running a Red Light
Running a red light is one of the most common traffic violations in California, yet it carries significant legal, financial, and safety consequences. California Vehicle Code § 21453 (CVC 21453) outlines the responsibilities of drivers when approaching intersections controlled by red lights or red arrows.
This detailed guide covers what the law states, the risks of red light violations, penalties for noncompliance, possible legal defenses, and practical tips to ensure safe and lawful driving behavior at intersections.
What Does California Vehicle Code § 21453 State?
CVC § 21453 provides specific rules about how drivers must behave when encountering traffic signals. Below is a breakdown of its main provisions:
1. Red Circular Signal – CVC 21453(a)
When facing a steady circular red signal:
Drivers must come to a complete stop at the marked limit line.
If no limit line is present, the stop must occur before the crosswalk.
If there is no crosswalk, the stop must be made before entering the intersection.
Drivers must remain stopped until a signal indicates they may proceed.
2. Right Turn on Red – CVC 21453(b)
California permits a right turn on red under specific conditions:
The driver must first come to a complete stop.
The turn may be made only when safe, and drivers must yield to all pedestrians and vehicles with the right-of-way.
The turn must not be made if there is a posted sign prohibiting a right turn on red.
Additionally, a driver may turn left on red from a one-way street onto another one-way street, following the same safety requirements.
3. Red Arrow – CVC 21453(c)
If facing a steady red arrow, a driver must:
Not enter the intersection to make the movement indicated by the arrow.
Stop completely and wait until the signal allows movement in the direction of the arrow.
4. Pedestrian Rules – CVC 21453(d)
Pedestrians must not enter the roadway during a steady red or red arrow signal unless a pedestrian control signal indicates otherwise, as provided in California Vehicle Code § 21456.

Why Running a Red Light Is Dangerous
Red light violations are considered hazardous because they increase the risk of severe accidents, often involving pedestrians, cyclists, or cross-traffic.
Intersection Collisions
Running a red light significantly increases the likelihood of T-bone or side-impact crashes. These types of collisions are more likely to cause serious injuries or fatalities due to limited vehicle protection from the side.
Pedestrian and Cyclist Risks
Pedestrians rely on red signals to safely cross the road. Vehicles that ignore red lights can cause fatal accidents with law-abiding pedestrians and cyclists.
Reduced Reaction Time
Drivers who run red lights are often distracted or speeding, reducing their reaction time and increasing the chances of missing critical visual cues at intersections.
Penalties for Violating CVC § 21453
Violating California’s red light laws can lead to a range of legal and financial consequences:
Monetary Fines
The base fine for a red light violation is $100.
With court fees, assessments, and surcharges, the total cost typically ranges from $490 to $550.
Violations caught by red light cameras carry similar penalties.
DMV Points
A red light violation adds 1 point to your Department of Motor Vehicles (DMV) driving record.
Accumulating 4 or more points within 12 months can lead to a license suspension under the Negligent Operator Treatment System (NOTS).
Traffic School
Eligible drivers may attend traffic school to prevent the point from being visible to insurers or employers.
Traffic school eligibility generally applies if the violation did not involve an accident or commercial vehicle.
Insurance Rate Increases
Insurance companies typically view red light violations as indicators of risky driving behavior, which may lead to higher premium rates for at least three years.
Defenses Against a Red Light Ticket in California
Receiving a ticket for a red light violation doesn’t automatically mean you’re guilty. Some valid legal defenses include:
1. Obstructed or Malfunctioning Signal
If the red light was blocked by trees, construction equipment, or other obstructions—or was not functioning correctly—the citation may be disputable.
2. Emergency Situations
Running a red light due to a medical emergency, road hazard, or to yield to an emergency vehicle can be a legally acceptable reason for the violation.
3. Mechanical Failure
Sudden brake failure or other vehicle malfunctions may serve as a defense if there’s verifiable evidence (e.g., repair receipts or expert testimony).
4. Insufficient Evidence
In some cases, especially involving red light cameras, there may be insufficient or unclear evidence. If law enforcement cannot prove the driver’s identity or the circumstances clearly, the ticket may be dismissed.
How to Avoid Red Light Violations
Avoiding a red light ticket—and the potential dangers that come with it—is possible through proactive and responsible driving. Here are practical tips:
Approach intersections cautiously. If the light has been green for a while, be prepared for a possible change.
Always make a complete stop before turning right on red. Rolling stops are both illegal and unsafe.
Yield to pedestrians and cyclists. Even when turning on red, you must give them the right of way.
Avoid distractions. Using a phone, eating, or any other distraction increases your risk of missing traffic signals.
Look both ways before entering an intersection, even on green, to ensure cross-traffic isn’t running a light.
Obey all posted signs, especially “No Turn on Red” or warnings about red light cameras.
Frequently Asked Questions
1. Can I turn right on red in California?
Yes, unless a posted sign prohibits it. You must make a full stop and yield to pedestrians and oncoming traffic before proceeding.
What if the light turns red after I enter the intersection?
If you entered on yellow and the light turned red while you were already in the intersection, you are generally not in violation.
2. Will a red light camera ticket go on my driving record?
Yes. It is considered a moving violation and results in 1 DMV point, unless dismissed or masked through traffic school.
3. How can I contest a red light ticket?
You can request a court hearing to challenge the ticket. Present evidence such as dashcam footage, witness statements, or proof of vehicle malfunction.
Conclusion
California Vehicle Code § 21453 plays a vital role in maintaining safety and order on the state’s roads. Running a red light not only increases the risk of collisions but also carries serious legal and financial consequences.
By understanding the law and consistently practicing safe driving habits, motorists can avoid costly tickets, preserve clean driving records, and most importantly, protect the lives of themselves and others.
