Safety - Commercial Driver's License (General Knowledge)

Hazard is a broad term that refers to any road condition or driver that could potentially cause danger. Hazardous materials are toxic or flammable. A patch of ice and a drunk driver are both considered hazards, by this definition.

In assessing your safe speed on a downgrade, your primary concern must be the safety of yourself and the other drivers or pedestrians nearby. The fragile nature of your cargo is far from the greatest concern, as compared to safe travel for all humans involved or nearby.

The best thing to do is, rather obviously, to place markers on the road to help other cars avoid running into the accident site. Leaving the car and signaling with your arms is nowhere near as efficient as a highly visible, and well-placed marker.

Once the temperature dips below freezing, you should just become generally more cautious/vigilant for slippery areas of the road. But, the MOST dangerous area of the ones listed is clearly bridges, which are among the first areas of the road to gather thin slippery layers of ice.

This is a simple definition question. Stopping distance is the combination of all the stopping related distances, perception, reaction, and braking.

The main indicator that your vehicle is equipped with an ABS is the yellow malfunction light in your instrument panel. If your vehicle is to code, and it was produced after March 1998 it should be equipped with an ABS. Also, you can always just physically get out of the cab and look at the back of your brakes for the telltale presence of wheel speed sensor wires. Your speedometer indicating both miles and kilometers per hour is not related to your ABS (it may mean your truck was manufactured in Canada).

The only purpose listed that is true of ABS is that they are designed to prevent a vehicles brakes from locking. Obviously this is more important for large or heavy vehicles, whose brakes lock more easily than other vehicles, and which pose a much greater threat when moving across a road with locked brakes.

The basics of shifting gears are as follows: release the accelerator, push the clutch, shift into neutral, release the clutch, let the engine and gears slow sufficiently, then push in the clutch and shift into the appropriate higher gear, release the clutch and LAST press the accelerator. Pressing your accelerator should always be the last step in this process.

In order for it to be remotely safe to remove your radiator cap, the entire engine system must be completely cooled. Even in that condition, removing the radiator cap should be only be done with extreme caution.
