Can heavy vehicles use the left lane of a highway?

Heavy vehicles should generally stay in the right lane of a highway unless they are passing another vehicle. This is based on the principle that the left lane is primarily designated for overtaking slower-moving traffic. Allowing heavy vehicles to use the left lane only for passing helps maintain traffic flow and reduces the likelihood of congestion or hazardous situations caused by slower trucks traveling in the faster left lane. This practice is also important for safety, as heavy vehicles typically have longer stopping distances and take more time to maneuver, making it critical that they stay in lanes that are appropriate for their speed and size. By adhering to these guidelines, drivers can ensure a smoother and safer driving experience for everyone on the road.
