Which of the following should be avoided to maintain safety while driving doubles/triples?

Answer: A — Frequent lane changes

Frequent lane changes should be avoided when driving doubles or triples due to the complexities and challenges associated with maneuvering longer combinations of vehicles. These larger configurations require more space to operate safely, and frequent changes in lanes can increase the risk of collisions, as they often involve blind spots that are more pronounced than those in a standard single truck. Moreover, frequent lane changes can disrupt the flow of traffic and create uncertainty for other drivers on the road. In contrast, maintaining a safe following distance is critical for allowing adequate stopping time, proper signalling during turns is essential for communicating intentions to other road users, and using turn signals is a fundamental practice for safe driving. These actions contribute to overall safety and help ensure that the driver and other road users have clear expectations regarding vehicle movements. Therefore, avoiding frequent lane changes is a key aspect of safely operating doubles and triples.
