22349(b) Speeding on Two-Lane Undivided Highways

CVC 22349b sets the speed limit for two-lane highways in California at 55 mph unless otherwise posted. Exceeding this limit increases the risk of a car accident, especially on roads with limited passing opportunities and high-speed traffic. Drivers who ignore these restrictions can face fines, points on their license, and heightened liability in crash-related claims.

What Is CVC 22349b?

CVC 22349b sets a maximum speed limit of 55 miles per hour on two-lane, undivided highways in California unless a higher limit is posted. This law is designed to prevent high-speed crashes, reduce head-on collisions, and improve road safety on highways with no physical barriers between opposing lanes. If a driver exceeds this limit, they can face fines, points on their license, and liability if their speeding results in an accident.

The official language of the statute reads as follows:

(b) Notwithstanding any other provision of law, no person may drive a vehicle upon a two-lane, undivided highway at a speed greater than 55 miles per hour unless that highway, or portion thereof, has been posted for a higher speed by the Department of Transportation or appropriate local agency upon the basis of an engineering and traffic survey.

This statute applies to all vehicles traveling on two-lane highways, ensuring that drivers maintain safe speeds on roads where passing is limited and visibility may be restricted.

Why California Restricts Speeds on Two-Lane Roads

Two-lane highways pose a higher risk of serious collisions due to narrow lanes, lack of barriers, and limited passing opportunities. Higher speeds increase stopping distances and make it harder to avoid head-on crashes, especially when drivers attempt to pass slower vehicles.

Differences Between CVC 22349b and Other California Speed Laws

CVC 22349b specifically applies to two-lane, undivided highways, but other speed limit laws regulate different types of roadways:

• CVC 22349a – Sets the general maximum speed limit at 65 mph on highways unless otherwise posted.
• CVC 22356 – Allows the speed limit to be raised to 70 mph on certain designated highways.

If a driver violates CVC 22349b by driving above 55 mph on a two-lane road, they can be ticketed even if no accident occurs. However, if speeding leads to a crash, the violation can be used as evidence of negligence in a personal injury claim.

Penalties for Violating CVC 22349b

Speeding on a two-lane highway can lead to traffic citations, fines, and DMV points. If a driver is involved in an accident while violating CVC 22349b, they may also face civil liability for injuries and damages. Legal statutes related to CVC 22349b could include:

• California Vehicle Code § 42000 – Outlines base fines for speeding violations and potential traffic school eligibility.
• California Vehicle Code § 12810 – Assigns DMV points for speed-related offenses, which can lead to higher insurance rates or license suspension.
• California Vehicle Code § 22350 – Prohibits driving at unsafe speeds regardless of the posted limit, which may apply in cases of reckless driving.

Common Defenses Against a CVC 22349b Violation

Drivers cited for violating CVC 22349b may have legal defenses depending on how their speed was measured and whether they had a valid reason for exceeding the limit.

Challenging the Accuracy of Speed Detection Methods

Law enforcement officers use radar, LIDAR, and pacing techniques to determine vehicle speeds. However, these methods can be challenged if:

• The radar or LIDAR device was not properly calibrated.
• The officer lacked clear visibility of the vehicle in question.
• Other vehicles interfered with the speed reading.

Proving a Legitimate Emergency Required Higher Speed

In some cases, exceeding the speed limit may be justified if the driver was responding to a medical emergency or attempting to avoid a road hazard. Courts may consider whether the situation warranted the higher speed and whether the driver took reasonable precautions while exceeding the limit. However, drivers must still prove that their actions were necessary and that they did not put others at risk by speeding excessively.

Situations Where CVC 22349b Applies

CVC 22349b is strictly enforced on two-lane highways where excessive speed increases the risk of severe accidents. Many of these roads lack median dividers, have limited passing zones, or are frequently used by slow-moving vehicles. Drivers who exceed the posted speed limit on these roads can face citations, fines, and liability in accident claims. Some of the most relevant roads and situations where CVC 22349b may apply include:

• Two-lane rural highways with high accident rates – Many rural roads have sharp curves, limited visibility, and higher crash risks, making speed enforcement crucial.
• Undivided roads with limited passing zones – Speeding in areas without safe passing lanes increases the likelihood of head-on collisions.
• Areas with sharp curves or blind turns – Speed limits are lower in areas where sight distance is reduced, preventing lane departure accidents.
• Roads frequently used by farm vehicles or cyclists – Many two-lane highways share space with slow-moving agricultural equipment or bicycles, making excessive speed dangerous.
• High-speed zones near residential areas – Some highways pass through towns or school zones, where pedestrian crossings and local traffic require slower speeds.

These roads have stricter speed limits than freeways because they lack safety barriers, have frequent stop points, and require lower speeds to reduce accident severity. Speeding on these highways can be especially dangerous when road conditions change suddenly due to weather, wildlife, or slow-moving vehicles.

How Speed Limits on Two-Lane Highways Are Determined

Speed limits on two-lane highways are not chosen at random. They are based on traffic studies, roadway design, and accident data. Transportation engineers evaluate road conditions and driver behavior to set safe speed limits that reduce crash risks.

Role of Engineering and Traffic Surveys in Speed Limit Decisions

Before setting or adjusting speed limits, California requires engineering and traffic surveys to analyze road conditions, accident history, and traffic flow. These studies help determine:

• The safest speed for the majority of drivers based on actual road use.
• Whether the current speed limit is too high or too low for existing traffic patterns.
• Where additional safety measures, like passing zones or speed enforcement, may be needed.

If a survey finds a high rate of speed-related crashes, transportation officials may lower the speed limit or install additional warning signs to improve safety.

Factors That Justify Lower Speed Limits in Certain Areas

Speed limits on two-lane highways vary based on environmental and traffic factors. Some of the key reasons why speed limits may be set lower include:

• High crash rates due to speeding or unsafe passing – If a highway has frequent collisions, lowering the speed limit helps reduce accident severity.
• Narrow lanes and lack of shoulders – Many rural highways do not have enough space for safe maneuvering, making lower speeds necessary for driver control.
• Frequent intersections and driveways – Roads that connect multiple local access points need slower speed limits to prevent rear-end and side-impact crashes.
• Wildlife crossings and poor lighting – Some roads pass through forest areas or unlit highways, where drivers need extra time to react to sudden obstacles.

How CVC 22349b Affects Traffic Safety in California

Speeding on two-lane highways significantly increases the risk of fatal crashes, particularly head-on collisions, rollovers, and loss of control incidents. Enforcing CVC 22349b helps reduce these risks by ensuring drivers maintain safe speeds on roads that lack physical dividers and have limited escape routes. Speed limits reduce traffic accidents by:

• Lowering crash severity in head-on collisions – Two-lane highways lack center dividers, making head-on crashes more likely at high speeds.
• Preventing loss of vehicle control on narrow roads – Speeding on roads with tight curves or limited shoulders increases the risk of run-off-road accidents.
• Reducing the risk of hydroplaning and weather-related crashes – High speeds increase stopping distances and make it harder to control a vehicle in rain, fog, or icy conditions.
• Allowing more time for evasive actions in wildlife-heavy areas – Many two-lane roads pass through rural or mountainous regions, where drivers must react quickly to avoid deer, coyotes, and other animals.
• Minimizing conflicts between high-speed vehicles and slower traffic – When drivers exceed the speed limit, they increase the risk of rear-end collisions with slower-moving vehicles, farm equipment, or cyclists.

Proving Fault in an Accident Related to CVC 22349b Violations

If a driver was speeding on a two-lane highway in violation of CVC 22349b, they could be held responsible for any resulting accidents. Speeding reduces reaction time, increases stopping distances, and makes head-on collisions more severe. To prove fault in an accident, you need clear evidence that shows the at-fault driver was exceeding the speed limit and acting recklessly. Some of the most important types of evidence used in CVC 22349b speeding accident cases include:

• Speed camera or radar gun readings from law enforcement – If a driver was caught speeding by an officer using a radar or LIDAR device, this evidence can help establish liability.
• Dashcam footage showing reckless driving behavior – Video footage can prove that the driver was weaving through traffic, tailgating, or speeding before the crash.
• Skid marks and accident reconstruction reports – Investigators analyze skid marks, impact points, and braking distances to determine how fast the driver was going at the time of the collision.
• Witness statements confirming excessive speed – If other drivers or pedestrians saw the at-fault driver speeding, their testimony can strengthen your claim.
• Road conditions and posted speed limit signs – If the driver was speeding in an area with sharp turns, poor visibility, or heavy traffic, this increases their level of fault.

Tip

If you were injured in an accident caused by a speeding driver on a two-lane highway, request a copy of the police report. If the driver was cited for violating CVC 22349b, this serves as strong evidence of negligence, making it easier to prove fault in your injury claim.

Consequences of Speeding on Two-Lane Highways

Speeding on undivided two-lane highways increases the risk of severe crashes, particularly head-on collisions, and loss of control accidents. These roads lack median barriers, making it easier for a speeding driver to drift into oncoming traffic or lose control on curves.

Increased Risk of Head-On Collisions

Head-on collisions are among the deadliest types of crashes, and speeding on two-lane highways makes them even more dangerous. When a driver exceeds the speed limit, they have less time to react if another vehicle crosses into their lane.

Many head-on crashes occur when a speeding driver tries to pass another vehicle in a no-passing zone. If they misjudge the distance or fail to see an oncoming car, the result is often a high-impact collision with devastating consequences. The faster the vehicles are moving, the more severe the injuries for everyone involved.

Pro Tip

Head-on collisions caused by speeding often result in severe injuries and high medical expenses. If the at-fault driver was recklessly passing in a no-passing zone or driving at extreme speeds, you may be eligible for punitive damages in addition to compensation for medical bills and lost wages.

Reduced Reaction Time in Hazardous Road Conditions

Two-lane highways often pass through rural areas, mountains, and roads with unpredictable conditions. Speeding in these areas increases the likelihood of hydroplaning, rollovers, and loss of control.

Note

Insurance companies may try to argue that speeding was not the primary cause of the accident to limit their payout. If the at-fault driver was traveling well above the posted speed limit, accident reconstruction experts can analyze skid marks, impact damage, and vehicle positioning to prove that speeding was a direct factor in the crash.
