What are the door locks for?
Door locks are a very important and overlooked feature on modern vehicles. They serve a number of functions to improve safety and security.
Locking the doors prevents strangers and passersby from simply entering the vehicle. This is helpful when the vehicle is occupied or unoccupied.
In the event of a crash, locked doors are less likely to fly open under extreme force. Locking the doors while driving also prevents passengers from opening the doors and falling out.
In a worst case scenario, a child could get into a vehicle that is unlocked and find themselves unable to get out, possibly due to child safety locks being activated. This is extremely hazardous, doubly so in hot weather.
