Question 19: When you are getting ready to drive, you should
Leave the doors of your vehicle unlocked until you start moving.
Lock all the doors of your vehicle before you start the engine.
Lock the doors of your vehicle only if you will be driving faster than 30 miles per hour.
Typically the answer would be none of the above as for newer cars have an automatic door lock but since of course it requires you to answer one of the options, in my opinion it would be “B”.
