Next, let’s look at the circumstances where passing is allowed.
- In the example below, a car traveling eastbound (toward the right) is permitted to pass a slower-moving car once it reaches the broken (or dashed) yellow line.
- Before deciding to pass, a driver must be able to see the left lane and ensure that no traffic is approaching in the oncoming direction.
- Drivers should also consider the speed of the vehicle that they wish to pass.
- If Driver A is traveling at 27 mph in a 30 mph zone and Driver B wants to travel at 30 mph, Driver B could legally pass, but it would take him a very long time to complete the passing maneuver.
- All passing must be performed within the speed limit. As a result, Driver B would end up passing Driver A at a speed that is only 3 mph greater than Driver A’s speed.
- For reference, an average person walks at about 3 mph. Passing in this instance might be legal, but it would be ill-advised and unsafe.
