    The correct answer is "HAVING A SIGN ON EACH SIDE SHOWING FOR WHOM THE VEHICLE IS BEING OPERATED". This is because all rented or leased commercial vehicles must have a sign on each side showing for whom the vehicle is being operated, unless exempted by law. This requirement helps to identify the owner or operator of the vehicle and ensure accountability. It also helps in case of any accidents or incidents involving the vehicle, as it provides clear information about the responsible party.

It is unlawful to coast in a commercial vehicle while going downhill because it can lead to a loss of control over the vehicle, especially when carrying heavy loads. Coasting can increase the risk of accidents, as the driver may not be able to respond quickly to unexpected situations. Therefore, it is important to use the appropriate lower gear and engine braking techniques to maintain control and ensure the safety of the vehicle and its occupants.

    CLEARANCE LAMPS MOUNTED ON THE REAR OR ON THE SIDE NEAR THE REAR OF THE VEHICLE MUST BE WHAT COLOR?

    • A.

      AMBER

    • B.

      WHITE

    • C.

      RED

    • D.

      GREEN

    Correct Answer
    C. RED
    Explanation
    Clearance lamps mounted on the rear or on the side near the rear of the vehicle must be red. This is because red is the standard color used for rear-facing lights on vehicles. Red lights indicate the rear position of the vehicle and help other drivers to see it clearly, especially in low visibility conditions. Using any other color, such as amber, white, or green, for these clearance lamps would not meet the standard safety requirements and could lead to confusion on the road.
