What action is recommended for heavy vehicles on multi-lane highways?

Staying close to the right edge of the road is recommended for heavy vehicles on multi-lane highways because it enhances safety and smooth traffic flow. Heavy vehicles, such as trucks and buses, generally have slower acceleration and reduced maneuverability compared to smaller, lighter vehicles. By keeping to the right, these vehicles minimize the chance of impeding faster traffic that typically uses the left lanes for overtaking.

In addition, this practice helps prevent congestion and allows for safer lane changes by other drivers who may want to pass. It also provides better visibility and space for emergency vehicles that may need to navigate through traffic. Overall, maintaining a position closer to the right edge of the road contributes to overall road safety and efficiency on highways.
