Intersection Accidents: How Fault and Liability Are Determined

Intersections are among the most common locations for serious car accidents, largely because they involve multiple vehicles crossing paths, turning, and making split-second decisions about right-of-way. When a collision happens at an intersection, determining fault often comes down to carefully reconstructing exactly what happened in the seconds before impact, since more than one driver can share responsibility for the same crash.

Traffic Signals and Right-of-Way Rules

Right-of-way rules form the backbone of intersection fault analysis. A driver who runs a red light, fails to yield when required, or turns left across oncoming traffic without a safe gap is typically found at fault for a resulting collision. Even at intersections without traffic signals, established right-of-way rules, such as yielding to the vehicle that arrived first at a four-way stop, determine which driver had the legal right to proceed.

How the California Vehicle Code Applies

California's Vehicle Code lays out specific rules governing right-of-way, permitted turns, and driver responsibilities at intersections, and violations of these rules are frequently cited as evidence of negligence in a resulting injury claim. For example, a driver making a left turn is generally required to yield to oncoming traffic unless protected by a green arrow, and a driver approaching a stop sign must come to a complete stop and yield to cross traffic and pedestrians already in the intersection.

Comparative Negligence in Intersection Cases

Intersection accidents frequently involve shared fault, since one driver might have been speeding while another failed to yield properly. California follows a pure comparative negligence system, meaning an injured driver can still recover compensation even if they were partially at fault, though their recovery is reduced by their percentage of responsibility. This makes a careful, evidence-based fault analysis especially important in intersection cases, where insurers often try to assign a larger share of blame to the injured party.

Evidence That Helps Establish Fault

• Red light camera or intersection surveillance footage
• Police accident reports and officer observations
• Witness statements from drivers, passengers, or pedestrians
• Vehicle damage patterns consistent with a specific point of impact
• Traffic signal timing records

Because intersection accidents so often involve competing accounts of who had the right-of-way, building a claim on solid evidence rather than assumptions is essential. Gathering documentation quickly, before footage is deleted and memories fade, gives injured drivers the strongest possible position when fault is disputed.
