When a vehicle towing a trailer skids and its trailer pushes from behind, it causes it to collide with its own trailer.The jack knifed vehicle could cause more accidents.There is an explanation of how to prevent jackknifing.
Step 1: Understand the causes of jackknifing.
It happens when the skids.The towing vehicle will be pushed until it spins around if the driver is not able to correct it in time.
Step 2: It is not the same as trailer slew or trailer swing.
The difference is here.
Step 3: Light loads can be very dangerous.
A heavy vehicle is not likely to jackknife.When the weight of the load is badly distributed, jackknifes can occur, providing too little traction where it’s needed.The brakes on the vehicle and trailer are designed for a full load.The wheels could lock up if strong brakes are applied.
Step 4: Reduce your speed gradually by spreading your braking over the longest possible distance.
It helps to drive a safe distance behind other vehicles and to try to anticipate what may happen ahead, allowing you plenty of time to pull up, especially on slippery roads and when you’re going downhill.
Step 5: Don’t have to decelerate on a curve.
As you approach a curve, apply your brakes while the vehicle is traveling in a straight line.Release your brakes before you start the turn.As you turn, apply a little power.The drive wheels should not lose traction.You will be able to speed up as you negotiate the curve if you approach slowly.Downhill turns are prone to jackknife.Don’t assume that the trailer will follow you down a steep hill if you want to turn left or right.The trailer is trying to go down the hill straight.You have to slow it down or stop before you turn.You can check the trailer’s momentum when you’re satisfied with it.
Step 6: Don’t brake and swerve at the same time if you need to avoid action.
Release the brakes if you want to slow the vehicle down as much as possible.You will remain in control of the vehicle in this way.If necessary, you can re- apply the brakes after you’ve swerved.If a child runs into the road in front of your truck, don’t stamp on the brake pedal.You should press it.Press the clutch pedal to stop the truck.Hold the steering wheel with your hands in the 10 minutes to 2 position, keeping your thumbs out of the wheel.Press them against the rim.
Step 7: Don’t use your engine brake or retarder if you’re very cautious.
There is a slippery surface.The drive axle could be locked up.The brakes act on all of the wheels, whereas the engine brake only acts on one axle.If the road is slippery and you need to use the retarder, slow the vehicle down and apply it carefully.If you were to engage a low gear, the same would apply.
Step 8: If you want to avoid skidding, jackknifing starts as a skid.
If your vehicle starts to skid, take your foot off the brake and correct the skid as you would with a rigid vehicle.The trailer pushing from behind will make it worse if it isn’t corrected.
Step 9: Take care of the tractor and trailer.
Uneven brakes, worn tires and faulty suspension components increase the risk of losing control.
Step 10: Heavy vehicles are fitted with modern anti-lock braking systems.
They can sense tire skid and adjust their brakes to prevent wheel lockup.
