FREE Basic ELDT Questions and Answers
On a steep descent, applying brakes is:
Explanation: While engine braking can assist in slowing down a vehicle on a steep downgrade, the use of brakes is typically necessary to supplement the braking effect of the engine. Brakes provide additional control and can help maintain a safe speed while descending a steep grade. It's important to use brakes judiciously and in conjunction with engine braking to ensure safe descent without overheating the brakes or losing control of the vehicle.
The speed restriction as posted:
Explanation: The posted speed limit is the maximum legal speed allowed on a specific road or highway under ideal conditions. Exceeding the posted speed limit is against the law and can increase the risk of accidents, injuries, and fatalities. Therefore, it is important to adhere to the posted speed limit at all times for the safety of yourself and others on the road.
If the trailer doors are heated when you find a fire, you should not open them for the following reasons:
Explanation: Introducing oxygen to a fire can cause it to intensify or spread rapidly. Therefore, opening the doors when they are hot could potentially increase the severity of the fire or create hazardous conditions. It's essential to exercise caution and follow appropriate procedures, which may include using a fire extinguisher or contacting emergency services for assistance.
As part of a pre-trip inspection, the driver should approach a car and check below for everything listed below, with the exception of:
Explanation: Inspecting for fresh oil, grease, and coolant under the vehicle is crucial as they could indicate leaks that need attention. However, windshield wiper fluid is typically stored in a separate reservoir and is not expected to be found under the vehicle during an inspection.
You should refrain from blowing your horn:
Explanation: While the horn can be used to alert others to potential problems or to your presence, it should not be used as a means to express frustration or anger towards other drivers for their mistakes. It's important to use the horn responsibly and only for legitimate safety reasons.
When brakes fail during a lengthy descent, you ought to:
Explanation: Escape ramps are specifically designed to help vehicles safely come to a stop in the event of brake failure on a long downgrade. It's crucial to follow proper procedures and use available resources to mitigate the situation and prevent accidents or injuries.
Which of the following DOES NOT indicate that you are tired?
Explanation: While the other options—yawning repeatedly, trouble keeping your head up, and trouble remembering the last few miles driven—are commonly recognized signs of fatigue, conversing with a passenger doesn't necessarily indicate fatigue. In fact, engaging in conversation might sometimes help a driver stay alert and focused on the road.
The majority of large cars need ________ shift gears.
Explanation: Most heavy vehicles require double clutching to change gears.
ABS intends to:
Explanation: ABS helps prevent wheel lock-up during braking, which can shorten stopping distances and increase overall control of the vehicle. Therefore, the statement "not give you more control over the vehicle during braking" is incorrect.
Engine belt looseness will:
Explanation: When engine belts are loose, they may slip on the pulleys they are connected to, causing components like the water pump and fan to operate inadequately. This can lead to insufficient cooling of the engine, resulting in overheating. Therefore, it's essential to ensure that engine belts are properly tensioned to maintain optimal engine function and prevent overheating.
What makes hydroplaning most likely to happen:
Explanation: When rainwater mixes with oil, grease, and other substances on the road surface, it creates a slick film that reduces friction between tires and the road. This can cause tires to lose contact with the road surface, leading to hydroplaning. Therefore, hydroplaning is most common during the initial stages of rainfall when the road surface is particularly slippery.
