Good Luck!

When starting down a hill, instead of using the foot brakes to control speed:

  • Engage the clutch and coast downhill
  • Engage the parking brake halfway down the incline

Special conditions where you should downshift are:

Before Starting Down a Hill —

Slow down and shift down to a speed that you can control without using the brakes hard. Otherwise the brakes can overheat and lose their braking power. Downshift before starting down the hill. Make sure you are in a low enough gear, usually lower than the gear required to climb the same hill.

Shifting gears on most heavy vehicles using manual transmissions will require:
  • Double-fisting

Basic Method for Shifting Up:

Most heavy vehicles with manual transmissions require double clutching to change gears. This is the basic method:

  • Release accelerator, push in clutch and shift to neutral at the same time.
  • Release clutch.
  • Let engine and gears slow down to the rpm required for the next gear (this takes practice).
  • Push in clutch and shift to the higher gear at the same time.
  • Release clutch and press accelerator at the same time.

To help slow the vehicle to reduce the need for using the service brakes, some vehicles are equipped with:

  • Emergency brakes
  • Parachutes

2.3.4 – Retarders

Some vehicles have "retarders," which help slow a vehicle and reduce the need for using the brakes. They reduce brake wear and give you another way to slow down. There are four basic types of retarders (exhaust, engine, hydraulic and electric).

All retarders can be turned on or off by the driver. On some vehicles the retarding power can be adjusted. When turned "on," retarders apply their braking power (to the drive wheels only) whenever you let up on the accelerator pedal all the way.

When activated, retarders apply braking power when:
  • The accelerator and brake are applied simultaneously
  • The road is icy or wheels have poor traction
  • The accelerator is let up all the way
  • The accelerator is applied all the way

2.15.5 – Crossing the Tracks

Railroad crossings with steep approaches can cause your unit to hang up on the tracks. Never permit traffic conditions to trap you in a position where you have to stop on the tracks. Be sure you can get all the way across the tracks before you start across. It takes a typical tractor-trailer unit at least 14 seconds to clear a single track and more than 15 seconds to clear a double track.

2.9 – Distracted Driving

Whenever you are driving a vehicle and your attention is not on the road, you are putting yourself, your passengers, other vehicles and pedestrians in danger. Distracted driving can result when performing any activity that may shift your full attention from the driving task.

Taking your eyes off the road or hands off the steering wheel presents obvious driving risks. Mental activities that take your mind away from driving are just as dangerous. Your eyes can gaze at objects in the driving scene but fail to see them because your attention is distracted elsewhere.

Activities that can distract your attention include: talking to passengers; adjusting the radio, CD player or climate controls; eating, drinking or smoking; reading maps or other literature; picking up something that fell; reading billboards and other road advertisements; watching other people and vehicles including aggressive drivers; talking on a cellphone or CB radio; using telematic devices (such as navigation systems, pagers, etc.); daydreaming or being occupied with other mental distractions.

2.9.3 – Watch Out for Other Distracted Drivers

You need to be able to recognize other drivers who are engaged in any form of driving distraction. Not recognizing other distracted drivers can prevent you from perceiving or reacting correctly in time to prevent a crash. Watch for:

  • Vehicles that may drift over the lane divider lines or within their own lane.
  • Vehicles traveling at inconsistent speeds.
  • Drivers who are preoccupied with maps, food, cigarettes, cellphones or other objects.
  • Drivers who appear to be involved in conversations with their passengers.

2.10.2 – Do not Be an Aggressive Driver

How you feel before you even start your vehicle has a lot to do with how stress will affect you while driving.

  • Reduce your stress before and while you drive. Listen to “easy listening” music.
  • Give the drive your full attention. Do not allow yourself to become distracted by talking on your cellphone, eating, etc.
  • Be realistic about your travel time. Expect delays because of traffic, construction or bad weather.
  • If you are going to be later than you expected – deal with it. Take a deep breath and accept the delay.
  • Give other drivers the benefit of the doubt. Try to imagine why they are driving that way. Whatever their reason, it has nothing to do with you.
  • Slow down and keep your following distance reasonable.
  • Do not drive slowly in the left lane of traffic.
  • Avoid gestures. Keep your hands on the wheel. Avoid making any gestures that might anger another driver, even seemingly harmless expressions of irritation like shaking your head.
  • Be a cautious and courteous driver. If another driver seems eager to get in front of you, say, “be my guest.” This response will soon become a habit and you won’t be as offended by other drivers’ actions.
