Arkansas Commercial Driver License (CDL) Practice Test

How often should you inspect tires in hot weather?

1. Every hour

2. Every time you stop

3. Every two hours or every 100 miles

4. Once a day

The correct answer is: Every two hours or every 100 miles

The correct answer outlines a recommended practice for tire inspections, particularly in hot weather when tire pressures can fluctuate significantly due to heat expansion. Inspecting tires every two hours or every 100 miles helps ensure that they remain within safe operating conditions. During long drives, especially in warmer climates, tires can heat up and lose air pressure, leading to increased risk of blowouts or tire failure. Regular checks within this time frame allow drivers to address any issues, such as low pressure or visible wear, before they escalate into more dangerous situations. Other options might suggest varying frequencies of inspections; however, they may not adequately account for the specific challenges posed by hot weather or the extensive travel involved. Being proactive with inspections at the recommended intervals ensures better safety and performance of the vehicle.
