Georgia Commercial Driver License Practice Test

What is important to do when driving in very hot temperatures?

1. Check oil levels every hour

2. Inspect your tires every 100 miles or 2 hours

3. Use air conditioning constantly

4. Reduce tire pressure

The correct answer is: Inspect your tires every 100 miles or 2 hours

When driving in very hot temperatures, inspecting your tires regularly, such as every 100 miles or every 2 hours, is crucial. High temperatures can cause tire pressure to increase, leading to an elevated risk of blowouts, especially if the tires are already worn or damaged. Regular inspections help ensure that tires are in good condition, sufficiently inflated, and free of any debris or damage, all of which promotes safety on the road. Other choices may reflect common maintenance practices, but they do not directly address the specific risks associated with hot weather driving. Checking oil levels every hour is not practical for most driving scenarios, as oil consumption doesn't typically fluctuate so rapidly. Using air conditioning constantly can lead to potential over-reliance on the vehicle’s cooling system, without addressing other important vehicle checks. Reducing tire pressure could compromise tire performance and safety, making it less advisable in high temperatures.
