A 2-minute lesson from the South Dakota course. Read the rules and examples, follow the handbook page references, and check your understanding before you move on.
An unsecured load can slide into traffic or fly off at speed, so it's both illegal and dangerous. Planning your trips well also saves money and wear on your car.
Know the rule
Driving with an unsecured load is against the law; if it causes a crash you may face a costly fine and jail time.
You're moving a mattress in a pickup. Tie it directly to the truck with straps, confirm nothing can shift or lift off in the wind, and double-check it before you drive away.
Check your understanding
Read the question, decide on an answer, then open it to check the explanation. These are Roadwise study questions based on the source handbook.
