Sample question from test 4
signs
If a WRONG WAY sign faces a driver who has just entered a ramp, what does it indicate?
- The vehicle is traveling against the permitted direction on the one-way street or ramp
- The lane is reserved for commercial trucks during rush hour
- The pavement ahead is rough but the travel direction is correct
- A detour requires the driver to continue until the next exit
Answer: The vehicle is traveling against the permitted direction on the one-way street or ramp. The WRONG WAY sign is placed farther down a one-way street or ramp to catch a driver who entered in the opposing direction. It is a direct warning about travel direction, not a pavement condition or vehicle classification. The safest response is to stop the conflict quickly without making a sudden maneuver: pull over safely, then turn around when the roadway and traffic permit. Treat the sign as urgent because opposing traffic may be approaching head-on.
