Under Maryland Transportation Code §21-601, drivers who make left turns must approach the intersection in the extreme left lane to traffic moving in the same direction. When the driver leaves the intersection, he or she must follow the flow of traffic. The driver must abide by traffic lights at an intersection. If the driver turns left on red and hits another driver, he or she is clearly liable for the crash. Left turns at a red light are only legal in certain situations, such as when the driver is turning left from a one-way street to another. Drivers who turn left at an intersection must also yield the right-of-way to any vehicle approaching from the opposite direction as laid out by Maryland Transportation Code §21-402. Cases like this can be tricky, and an attorney with experience navigating automobile accidents can be a great help when addressing such a claim.
