Before switching on the ignition, you should:
- Be sure only backseat passengers have buckled their seat belts.
- Be sure only adult passengers have buckled their seat belts.
- Be sure only child passengers have buckled their seat belts.
- Be sure all of the vehicle's occupants have buckled their seat belts. ✓
Answer: D. Be sure all of the vehicle's occupants have buckled their seat belts.
Before you switch on the ignition, make sure every person in the vehicle has buckled their seat belt.
Why this is the answer
The Texas handbook says the driver and every passenger must use a safety belt if they are in a seat that has one, and it says this applies no matter how old the person is. It also notes that child safety seats are required for certain younger children. Because the rule covers everyone in the vehicle, not just chosen groups, the pre-start check should include all occupants. The handbook also states that not using a belt is dangerous and against state law.
Why the other answers are wrong
- A. Be sure only backseat passengers have buckled their seat belts. — Checking only backseat passengers misses the driver and front-seat passengers, whom the handbook also requires to be belted.
- B. Be sure only adult passengers have buckled their seat belts. — Checking only adults leaves out children and other passengers, while the handbook applies the belt requirement regardless of age.
- C. Be sure only child passengers have buckled their seat belts. — Checking only children leaves out adults and the driver, who are also covered by the belt requirement.
Remember it
Think "driver plus everyone" when you buckle up before starting.
