- You should never assist the injured until authorities have arrived
- Assist the injured after you have protected the area, but before you have notified authorities
- Assist the injured only after you have protected the area and notified authorities
- Assist the injured immediately
Quote From The CDL Manual:
If a qualified person is at the accident and helping the injured, stay out of the way unless asked to assist. Otherwise, do the best you can to help any injured parties:
- Do not move a severely injured person unless the danger of fire or passing traffic makes it necessary.
- Stop heavy bleeding by applying direct pressure to the wound.
- Keep the injured person warm.
TruckingTruth's Advice:
If you are the first one on the scene of a serious accident, you may want to help the injured right away. But make sure you secure the scene of the accident first to avoid any additional collisions. You should then notify the authorities before attempting to assist an injured person. Make sure you memorize the order of recommended accident procedures:
1. Protect the area
2. Notify authorities
3. Assist the injured
- The rear tires have more tread than the front tires
- The rear tires have more friction than the front tires
- The rear drive wheels lock up
- The front wheels lock and the drive wheels do not
Quote From The CDL Manual:
Rear-wheel braking skids occur when the rear-drive wheels lock.
- Notifying authorities should be the first thing you do after an accident
- Assist the injured first, then notify authorities
- After the accident scene has been properly protected
- If you're involved in an accident, let someone else contact the authorities
Quote From The CDL Manual:
If you have a CB, put out a call over the emergency channel before you get out of your vehicle. If not, wait until after the accident scene has been properly protected, then phone or send someone to phone the police. Try to determine where you are so you can give the exact location.
TruckingTruth's Advice:
If you're in an accident, your initial reaction may be to call the authorities immediately. But many accidents result in a "secondary accident" and often times, those crashes are far more severe than the original accident. Before doing anything, try to secure the scene to avoid any secondary accidents, then contact the authorities. Make sure you memorize the order in which things should be done at an accident scene:
1. Protect the area
2. Notify authorities
3. Assist the injured
- Quickly steer in the opposite direction you want the vehicle to go
- Let the vehicle slow down without turning or braking hard
- Accelerate out of the skid
- Engage the parking brake so all wheels have even brake pressure
Quote From The CDL Manual:
When a front-wheel skid occurs, the only way to stop the skid is to let the vehicle slow down. Stop turning and/or braking so hard. Slow down as quickly as possible without skidding.
- Turn the steering wheel in the opposite direction you want the vehicle to go
- Apply more brake pressure to slow the vehicle down
- None of these answers are correct
- Keep the steering wheel firm and straight
Quote From The CDL Manual:
Rear-wheel braking skids occur when the rear-drive wheels lock. Because locked wheels have less traction than rolling wheels, the rear wheels usually slide sideways in an attempt to "catch up" with the front wheels. In a bus or straight truck, the vehicle will slide sideways in a "spin out." With vehicles towing trailers, a drive wheel skid can let the trailer push the towing vehicle sideways, causing a sudden jackknife.
Do the following to correct a drive-wheel braking skid:
- Stop braking This will let the rear wheels roll again and keep the rear wheels from sliding any further. If on ice, push in the clutch to let the wheels turn freely.
- Turn quickly When a vehicle begins to slide sideways, quickly steer in the direction you want the vehicle to go down the road. You must turn the wheel quickly.
- Countersteer As a vehicle turns back on course, it has a tendency to keep right on turning. Unless you turn the steering wheel quickly the other way, you may find yourself skidding in the opposite direction.
Learning to stay off the brake, turn the steering wheel quickly, push in the clutch and countersteer in a skid takes a lot of practice. The best place to get this practice is on a large driving range or "skid pad."
- Put road flares on the ground near disabled vehicles
- If possible, move your vehicle to the side of the road
- Set out reflective triangles to warn other traffic
- Activate your emergency flashers
Quote From The CDL Manual:
The first thing to do at an accident scene is to keep another accident from happening at the same spot.
- If your vehicle is involved in the accident, try to get it to the side of the road. This will help prevent another accident and allow traffic to move.
- If you are stopping to help, park away from the accident. The area immediately around the accident will be needed for emergency vehicles.
- Put on your flashers.
- Set out reflective triangles to warn other traffic. Make sure they can be seen by other drivers in time for them to avoid the accident.
- Do not put road flares on the ground near wrecked vehicles. Road flares could ignite any leaking flammable liquids.
TruckingTruth's Advice:
As long as you always practice safe driving techniques, you probably will never be involved in a major accident. However, it is very likely you'll see a major accident occur or be one of the first people on scene. First and foremost, remember to protect yourself. Many good samaritans end up injuring themselves by stepping into a traffic lane, slipping on fluids spilled onto the roadway, or cutting themselves on debris from the accident. Don't become another victim!
While using road flares may be ok in some situations, remember that after an accident, flammable liquids may leak and spread along the ground, so it's best to use warning devices which don't have an ignition source, such as reflective warning triangles.
- Cargo loaded so not enough weight is on the front axle
- All of these are reasons for front-wheel skids
- Driving too fast for conditions
- Too much tread on the front tires
Quote From The CDL Manual:
Front-Wheel Skids - Most front-wheel skids are caused by driving too fast for conditions. Other causes are lack of tread on the front tires, and cargo loaded so not enough weight is on the front axle. In a front-wheel skid, the front end tends to go in a straight line regardless of how much you turn the steering wheel. On a very slippery surface, you may not be able to steer around a curve or turn.
When a front-wheel skid occurs, the only way to stop the skid is to let the vehicle slow down. Stop turning and/or braking so hard. Slow down as quickly as possible without skidding.
- Help the injured out of their damaged vehicle
- Stop heavy bleeding by applying direct pressure to the wound
- Keep the injured person warm
- Do not move a severely injured person unless the danger of fire or passing traffic makes it necessary
Quote From The CDL Manual:
If a qualified person is at the accident and helping the injured, stay out of the way unless asked to assist. Otherwise, do the best you can to help any injured parties:
- Do not move a severely injured person unless the danger of fire or passing traffic makes it necessary.
- Stop heavy bleeding by applying direct pressure to the wound.
- Keep the injured person warm.
- Notify authorities, protect the area, assist the injured
- Protect the area, notify authorities, assist the injured
- Assist the injured, protect the area, notify authorities
- Protect the area, assist the injured, notify authorities
Quote From The CDL Manual:
When you are in an accident and not seriously hurt, you need to act to prevent further damage or injury. The basic steps to be taken at any accident are:
1. Protect the area.
2. Notify authorities.
3. Assist the injured.
TruckingTruth's Advice:
It's important to memorize this list in order as it is a frequently asked question on the DOT written exam. Also understand the meaning of each:
- Protect the area - The first thing to do at an accident scene is to keep another accident from happening at the same spot.
- Notify Authorities - If you have a CB, put out a call over the emergency channel before you get out of your vehicle. If not, wait until after the accident scene has been properly protected, then phone or send someone to phone the police. Try to determine where you are so you can give the exact location.
- Assist the injured - If a qualified person is at the accident and helping the injured, stay out of the way unless asked to assist. Otherwise, do the best you can to help any injured parties:
- Do not move a severely injured person unless the danger of fire or passing traffic makes it necessary.
