1. Driving with a cargo of hanging meat in a trailer:

An operator should drive with care when transporting a cargo of hanging meat. Such a load is unstable, both because it has a high center of gravity and because the swinging of the meat can affect the driver's handling of the vehicle.
2. Oversized loads:
Explanation
Special permits are required for loads that are over-size, over-length, or overweight.
3. When traveling down a steep grade, you switch into a lower gear:
Explanation
You should shift your vehicle's transmission into a low gear before staring a downhill grade. Be prepared for gravity to increase your vehicle's speed when traveling downhill.
4. If a tire fails, you should:

5. If a driver begins to feel fatigued while driving, they should:
Explanation
If you begin to feel drowsy while driving, the only safe response is to safely leave the road and get some sleep. Using artificial stimulants can be dangerous because they may cause extreme fatigue when they begin to wear off.
6. Cargo with a high center of gravity:

Cargo with a high center of gravity makes a vehicle more likely to tip over than cargo with a low center of gravity. For this reason, it is important that the weight of cargo be distributed as low as possible.
7. Hanging meat as a cargo:
