Final answer:
Drivers must maintain a constant speed when passing and reentering the lane in front of trucks or buses because trucks and buses require longer distances to slow down than cars.
Step-by-step explanation:
When passing and reentering the lane in front of trucks or buses, drivers must maintain a constant speed because trucks and buses require longer distances to slow down than cars.
Trucks and buses are much larger and heavier than cars, which means they have more momentum. This means that it takes them longer to slow down or come to a complete stop compared to cars.
By maintaining a constant speed, drivers give trucks and buses enough room and time to safely slow down and stop if necessary, reducing the risk of accidents or collisions.
Drivers must maintain a constant speed when passing and reentering the lane in front of trucks or buses because trucks and buses require longer distances to slow down than cars. Due to their larger mass and weight, trucks and buses have greater momentum, which means they cannot stop as quickly as smaller vehicles. When reentering the lane, it's important for drivers to ensure they have given a bus or truck enough space to respond to any changes in traffic speed safely.
