Where to Steer. If an oncoming driver has drifted into your lane, a move to your right is best. If that driver realizes what has happened, the natural response will be to return to their own lane. If something is blocking your path, the best direction to steer will depend on the situation.

If you have been using your , you will know which lane is empty and can be safely used.
If the shoulder is clear, going may be best. No one is likely to be driving on the shoulder, but someone may be passing you on the left. You will know if you have been using your .
If you are blocked on both sides, a move to the may be best. At least you will not force anyone into an opposing traffic lane and a possible head-on collision.

Leaving the Road. In some emergencies, you may have to drive off the road. It may be less risky than facing a collision with another vehicle. Most are strong enough to support the weight of a large vehicle and, therefore, offer an available escape route. Here are some guidelines, if you do leave the road:

Avoid . If possible, avoid using the until your speed has dropped to about mph. Then brake very gently to avoid skidding on a loose surface.
Keep one set of on the pavement, if possible. This helps to maintain control.
Stay on the . If the shoulder is clear, stay on it until your vehicle has come to a stop. Signal and check your mirrors before pulling back onto the road.

Returning to the Road. If you are forced to return to the road before you can stop, use the following procedure:

Hold the wheel tightly and turn enough to get right back on the road safely. Do not try to edge gradually back on the road. If you do, your might grab unexpectedly and you could lose control.
When both front tires are on the paved surface, immediately. The two turns should be made as a single “-” move.

2.17.2 – How to Stop Quickly and Safely

If somebody suddenly pulls out in front of you, your natural response is to hit the brakes. This is a good response if there is enough distance to stop and you use the brakes correctly. You should brake in a way that will keep your vehicle in a line and allow you to turn if it becomes necessary. You can use the “ braking” method or the “ braking” method.

Controlled Braking. With this method, you apply the brakes as as you can without locking the wheels. Keep steering-wheel movements very while doing this. If you need to make a larger steering adjustment or if the wheels lock, the brakes. Re-apply the brakes as soon as you can.

Stab Braking.

Apply your brakes .
brakes when wheels lock up.
As soon as the wheels start rolling, apply the fully again. (It can take up to one for the wheels to start rolling after you release the brakes. If you re-apply the brakes before the wheels start rolling, the vehicle will not straighten out.)

Do Not Jam on the Brakes. Emergency braking does not mean pushing down on the brake pedal as as you can. That will only keep the wheels locked up and cause a skid. If the wheels are skidding, you cannot control the vehicle.

2.17.3 – Brake Failure

Brakes kept in good condition rarely fail. Most brake failures occur for one of two reasons: (Air brakes are discussed in Section 5.)

Loss of pressure.
Brake on long hills.

Loss of Hydraulic Pressure. When the system will not build up pressure, the brake pedal will feel spongy or go to the . Following are things you can do:

Downshift. Putting the vehicle into a gear will help slow the vehicle.
Pump the Brakes. Sometimes pumping the brake pedal will generate enough hydraulic to stop the vehicle.
Use the Parking Brake. The parking or brake is separate from the hydraulic brake system. Therefore, it can be used to slow the vehicle. However, be sure to press the button or pull the lever at the same time you use the brake so you can adjust the brake pressure and keep the wheels from locking up.
Find an Escape Route. While slowing the vehicle, look for an escape route, an open field, side street or escape ramp. Turning is a good way to slow and stop the vehicle. Make sure the vehicle does not start rolling backward after you stop. Put it in gear, apply the parking brake and, if necessary, roll back into some that will stop the vehicle.
