California Vehicle Code sections 21451-21461 govern when and where drivers can legally make U-turns. Understanding these laws is essential for establishing liability in motorcycle U-turn accidents. Generally, U-turns are prohibited in business districts unless made at an intersection or on a divided highway where an opening is provided. Drivers must also ensure they can complete the U-turn safely without interfering with other traffic.
U-turns are specifically illegal in several situations: within 200 feet of an intersection controlled by a traffic signal, where a 'No U-Turn' sign is posted, on railroad crossings, on divided highways except at designated openings, and anywhere the driver cannot see clearly in both directions for at least 200 feet. When a driver violates these laws and causes a motorcycle accident, they are typically considered negligent per se, meaning their violation of the law establishes fault.
Even when U-turns are technically legal, drivers must still exercise reasonable care. This means checking all mirrors and blind spots, using turn signals, yielding to all oncoming traffic including motorcycles, and ensuring sufficient space and time to complete the maneuver safely. Failure to meet these standards can result in liability even if the U-turn itself wasn't illegal. For motorcyclists injured in these crashes, understanding these legal standards is crucial for building a strong personal injury claim.
