Trucks on hills and turns — South Carolina Permit Test

On steep hills large vehicles drive slowly in the right lane, so avoid the right lane on hills and near truck weigh stations if possible.

Cars in the right lane there meet slow trucks climbing or trucks pulling back into faster traffic.

Avoid driving in the right lane, if possible, when traveling up or down hills, as well as near truck weigh stations, where large vehicles will be attempting to re-enter faster moving traffic.

A truck or bus making a right turn may swing wide to the left; do not turn until it has completed its turn.

A car that slips between the truck and the curb is squeezed by the trailer as the turn finishes.

To avoid a collision, do not turn until the truck or bus has completed its turn.

When you meet a truck from the opposite direction, keep as far right as possible to avoid a sideswipe and reduce wind turbulence.

The air pushed between the two vehicles shoves them apart and can unsettle a car close to the center line.

When you meet a truck coming from the opposite direction, keep as far as possible to the right side of the roadway to avoid a side-swept collision and to reduce the wind turbulence between the two vehicles, which pushes the vehicles apart.

When in doubt about the speed of an oncoming truck or bus, do not turn left in its path.

Drivers misjudge how fast a big vehicle is coming, and it needs longer to stop than they expect.

When in doubt about the speed of an oncoming truck or bus, do not turn left in its path.

Always stop behind stop lines, which set you farther back to give larger vehicles more turning space.

A car stopped past the line sits in the path a turning truck's trailer has to sweep through.

These stop lines help to set you farther back at an intersection to give larger vehicles more turning space.

Do not cut off a large vehicle to reach an exit or turn, or to beat a truck into a single-lane construction zone.

A truck cannot stop in the gap you leave it, and the few seconds gained are not worth a life.

Do not cut off a large vehicle in traffic or on the highway to reach an exit or turn or to beat a truck into a single-lane construction zone.

Where does the manual advise avoiding the right lane, if possible?

On steep hills and near weigh stations. Cars in the right lane there meet slow trucks climbing or trucks pulling back into faster traffic. South Carolina Driver's Manual, p.119: “Avoid driving in the right lane, if possible, when traveling up or down hills, as well as near truck weigh stations, where large vehicles will be attempting to re-enter faster moving traffic.”
