JJ Keller Entry Level Driver Training For CDL (Commercial Driver’s License) Practice Test

Using plane (west coast) mirrors is the most suitable choice when you need to see down the sides and towards the rear of your trailer. These mirrors are designed with a larger surface area and a specific angle that allows drivers to achieve a broader view of their surroundings. This enables better visibility of the sides of the trailer and helps in identifying any potential hazards or vehicles in adjacent lanes, as well as providing a clearer view of the rear area around the trailer. In contrast, conex mirrors are primarily suited for different types of vehicles and may not provide the comprehensive visibility required for a tractor-trailer setup. Flat mirrors, while useful, do not offer the same level of viewing angle needed for trailers, often leading to blind spots. Blind spot mirrors are helpful for reducing blind spots but do not offer the extensive visibility that plane mirrors provide, especially when assessing the entire length of a trailer. The plane mirrors strike the right balance between size and angle, making them the preferred choice for ensuring safety while driving and maneuvering larger vehicles.
