Question 27 of 180

Pick an answer

That the interior lights are working properly
Mirrors aren't useful for this since the door has its own sensor, which is designed to stop the door if anything blocks its path
That it's safe to open the door, with no traffic or hazards immediately alongside the vehicle
That all seats are currently occupied

Correct answer to question 27 (Passenger): That it's safe to open the door, with no traffic or hazards immediately alongside the vehicle

Why

A passenger stepping out into a passing cyclist or vehicle is a real risk, so mirrors are what confirm the space right alongside the door is actually clear before it opens.
