Final answer:
The correct statement is that slow vehicles should use the right-hand lane except when passing or making a left turn. This is to ensure smooth traffic flow and road safety by keeping faster-moving traffic to the left. Ignoring speed limits and lane rules can increase risks of accidents on the road.
Step-by-step explanation:
The statement 'Slow vehicles should use the left-hand lane except when passing or making a left turn' is false. In the United States and in many other countries, the common rule of the road is that slower traffic should keep to the right-hand lane, while the left-hand lane is generally reserved for passing or turning left. This protocol helps maintain traffic flow and reduces congestion and accidents on roads. When slower vehicles use the right-hand lane, it allows faster-moving traffic to pass safely on the left, which is particularly important on multi-lane roads.
Speed limits are posted to promote safety and minimize the chances of accidents. Drivers who ignore speed limits and speed through intersections pose a risk to themselves and others. Traffic signals at intersections force drivers to slow down and reduce the possibility of speeding, intending to improve safety for all road users.
As highlighted in the anecdotal example, when someone drives at or below the minimum speed on a main road where most traffic is flowing faster, they can become a hazard, particularly if they are in the left-most lane and not actively passing or turning left. It's always important for all drivers to be aware of their surroundings and adhere to traffic laws and road safety protocols, which include correct lane usage.
