General Knowledge Flashcards
(50 cards)
When will help a drunk sober up?
Time
Your body breaks down alcohol at a predictable rate.
How do you test a vehicle’s hydraulic brakes for leaks?
Pump the brakes 3 times. Then apply firm pressure for 5 seconds.
If it moves, the brakes may have a leak or some other problem.
You have two tiedowns on a 17-foot load. How many MORE tiedowns do you need?
None
You should have one tiedown per 10 feet of cargo, and you must have at least two, regardless of the length. So for a 17 foot load, 2 tiedowns is enough.
Why should you cover your cargo?
There are several reasons to cover your cargo, including protecting other people and the cargo itself. In addition, it will help your comply with regulations in several states.
If you are convicted of __________, you will lose your CDL for at least one year if it was your first offense.
If you are convicted of a serious offense such as: refusing to undergo blood alcohol testing, driving a vehicle under the influence of a controlled substance and/or commiting a felony involving the use of a vehicle, you will lose your CDL for at least one year if it was your first offense. (If you were driving a CMV placarded for hazardous materials at the time of the offense, you will lose your CDL for at least 3 years.) If you are convicted for a second time, you will lose your CDL for life.
What colors should your side marker lights be?
Red at rear, others amber
Your side marker lights are red at the rear and amber elsewhere.
What are the basic methods for shifting up?
You must release the accelerator, press the clutch and shift into neutral at the same time, release the clutch, let the engine and gears slow to the required rpm for the next gear, press the clutch and shift into a higher gear at the same time, then release the clutch and press the accelerator at the same time. Acceleration is not involved until the very end, and definitely not while pressing the clutch.
You will lose your CDL for at least 60 days if you are convicted of two serious traffic violations involving a commercial motor vehicle (CMV) within a three-year period. Such violations include which of the following?
You will lose your CDL for at least 60 days if you are convicted of two serious traffic violations involving a CMV within a three year period, you will lose your CDL for at least 120 days. Such violations include speeding at 15 mph or more above the speed limit, driving recklessly, making improper or erratic lane changes, tailgating and texting or talking on a handheld cell phone.
Hazardous materials placards are:
signs on the outside of the vehicle that identify the hazard class of the cargo.
Hazardous materials placards are four regulated signs on the outside of the vehicle that identify the hazard class of the cargo for those who need to know, such as emergency service personnel or those who load and unload cargo.
If your vehicle has an automatic transmission, when should you select a low range?
Before entering a downgrade
If you keep applying the brakes to control your speed on a steep descent, the brakes will fade (lose their effectiveness). Instead, if your vehicle has an automatic transmission, select a low range that prevents the transmission from shifting up beyond the selected gear. This will generate a braking effect to slow the vehicle, known as engine braking. The lower the gear, the greater the engine braking effect. Apply the brakes only when engine braking is insufficient or you want to stop.
What are the main differences between aggressive driving and road rage?
whether it’s intentional
Aggressive driving is driving in a selfish or pushy manner, which is dangerous enough. Road rage is even worse: intentionally driving to threaten, attempt, or commit a violent act. Aggressive driving generally involves traffic infractions while road rage generally involves crimes.
What are the four basic skills that operating a commercial motor vehicle requires?
- Accelerating
- Steering
- Stopping
- Backing safely
How many reflective warning triangles must you carry with you for emergencies?
3
Your vehicle’s emergency equipment must include warning devices such as three reflectiving red triangles, three liquid flares, or six fusees.
During your pre-trip test, when examining hoses with the instructor, you need to look for
When you inspect hoses during your pre-trip test, you need to look for signs of leaks such as puddles on the ground or fluids that are dripping on the underside of the engine or transmission. Also check the hoses for cracks or other problems.
If you are being tailgated, what should you do?
Do not try to speed up to appease a tailgater. No speed is too fast for some tailgaters. Instead increase your following distance and if possible, keep right to let the tailgater pass.
When driving on packed snow, you should reduce your speed by at least
When a road is wet, stopping distance is increased, and you should reduce your speed by one-third. On packed snow, slow to one-half your usual speed or less. On icy roads, slow to a crawl and stop driving as soon as you can do so safely.
Perception distance is the distance that your vehicle travels
From when your eyes see a hazard to when your brain recognizes the hazard
You should inspect wheel bearing seals for
Leaks. The most likely problem with wheel bearing seals is leaking, so you should check for grease on the wheels and any visible evidence of cracks or leaks.
What is the gross vehicle weight (GVW)?
The total weight of a single vehicle and its load.
How often must you stop to check your cargo while on the road?
After each break you take, within the first 50 miles, every three hours or 150 miles.
When there’s a hazard ahead, it’s almost always quicker for you to _________ than to come to a full stop.
Steer clear of it. Large vehicles have long stopping distances. If your faced with a hazard ahead and you don’t have enough room to stop, try to steer away from the hazard. It’s usually quicker to turn away than to come to a full stop. (However, top-heavy vehicles and tractors with multiple trailers may flip over.)
Why is it important to use a helper when backing?
*Because you have blind spots. *
Before you start the two of you should agree on a set of hand signals for “go” and (most importantly) “stop.”
When should you not use retarders?
If your drive wheels have poor traction.
While retarders can help reduce the need for braking, they can make skid more likely on slippery roads. Therefore, you should turn off your retarders whenever the road is wet, icy, or snow-covered.
Total stopping distance equals
perception distance+reaction distance+braking distance
Total stopping distance is the sum of your perception distance (how far your vehicle goes from when you see the hazard until your brain processes it), reaction distance (how far the vehicle goes from when your brain orders your foot to take action until your foot actually starts to brake), and braking distance (how far the vehicle continues to travel once you apply the brake).
