Question 6633
In which of the following situations is it most helpful for the driver to have the rear cross-traffic alert system (RCTA) in their vehicle?
- When entering traffic from a perpendicular parking space without backing up.
- When entering traffic by backing up with reduced visibility.
- When starting the vehicle on an uphill slope, especially on a curve.
Show answer and explanation
Correct answer: When entering traffic by backing up with reduced visibility.
RCTA activates when you shift into reverse and uses sensors to monitor traffic approaching from the sides. It’s especially helpful when you’re backing out of a perpendicular parking space and can’t see the street, like the blue car in the image, squeezed between two vans as another car approaches. It doesn’t act if you drive out forward, and moving off on a hill is Hill Holder’s job.
