Texas DMV Written Driving Practice Test

Passing another vehicle on a two-lane roadway is only legal when the vehicle in front of you is going slower than the speed limit. Options A, B, and D do not provide a safe and legal opportunity to pass a vehicle. A roadway being curved can hinder a driver's visibility, making it unsafe to pass. A passing lane is typically designated for traffic going in one direction and does not guarantee a safe passing situation. Keeping at least one car length between your vehicle and the one in front of you is important for safety, but does not mean it is legal to pass. In order to pass a vehicle on a two-lane roadway, it must be done in a legal and cautious manner, such as when the vehicle in front of you is going slower than the speed limit.
