Vehicle Inspection and Safe Driving Techniques
- The most important reason for doing a vehicle inspection is to ensure the vehicle is safe to operate.
- During a trip, important things to check include gauges, mirrors, and the road ahead for potential hazards.
- Key steering system parts include the steering wheel, steering shaft, tie rods, and drag link.
- Suspension system defects can include cracked or broken spring hangers, leaking shock absorbers, and damaged or missing leaf springs.
- Three kinds of emergency equipment that should be carried are a fire extinguisher, reflective triangles, and spare electrical fuses.
- The minimum tread depth for front tires is 4/32 of an inch, and for other tires, it is 2/32 of an inch.
- During a walk-around inspection, it is important to check the headlights, turn signals, and the condition of the front bumper and grill.
- Wheel bearing seals should be checked for signs of leaks or damage.
- It is recommended to carry three red reflective triangles.
- To test hydraulic brakes for leaks, pump the brake pedal three times, then apply firm pressure for five seconds. The pedal should not move.
- Putting the starter switch key in your pocket during the pre-trip inspection prevents anyone from starting the engine while you are inspecting the vehicle.
- Factors that determine the selection of a "safe" speed when going down a long, steep downgrade include the weight of the vehicle, road conditions, weather, and the steepness of the grade.
- Being in the proper gear before starting down a hill is important to control the speed of the vehicle and prevent brake failure from shifting gears while descending.
- The proper braking technique when going down a long, steep downgrade is to use the engine brake or retarder whenever possible. If additional braking is needed, apply the brakes intermittently, not continuously, to avoid overheating them.
- Low-slung units, such as lowboy trailers or container chassis, can get stuck on a railroad-highway crossing.
- It takes a typical tractor-trailer unit about 15 seconds to clear a double track.
- Stopping may not always be the safest option in an emergency, especially if it can lead to a collision. In some situations, swerving or going to the side may be a better choice.
- Going right around an obstacle is usually safer than going left because of better visibility and less likelihood of oncoming traffic.
- An escape ramp is a specially designed area on steep mountain roads where vehicles can safely stop if they are experiencing brake failure or other emergencies while descending.
- If a tire blows out, it is recommended to stay off the brakes, grip the steering wheel firmly, and gradually reduce speed by easing off the accelerator.
- Vehicles equipped with antilock brakes will have an ABS malfunction lamp on the instrument panel.
- When driving a vehicle with antilock brakes, continuous, firm pressure should be applied to the brake pedal during hard braking. Pumping the brakes should be
