Question

Why should you open your door with your right hand when parked on a right-side curb?

A. They shouldn't. Opening the driver side door with your left hand is the safest.
B. So that you will be forced to look behind the car for an approaching bicyclist.
C. To make sure that you engage the parking brake with your left hand.
D. To stretch your back and spine in case you had poor sitting posture.

Answer 1

B. So that you will be forced to look behind the car for an approaching bicyclist.

Step-by-step explanation:

The main reason for opening with your right hand in this scenario is so you can look behind you for a bicyclist, etc. It's a good practice as you never know if someone is behind you or of the likes. Many people usually open the door with their left hand. The problem with this is that they're not forced to look behind them and can be oblivious to people, bicyclists, etc. behind them.

Hope this helps and have a nice day!
