What should you do if a truck signals to change lanes?

When a truck signals to change lanes, moving to the adjacent lane to give them space is the appropriate action to take. Trucks are larger vehicles that require more room to maneuver, and they typically have larger blind spots compared to smaller vehicles. By moving to the adjacent lane, you are allowing the truck to safely change lanes without the risk of an accident. This behavior promotes safer driving conditions for everyone on the road, as it shows consideration for the needs of larger vehicles that may need additional space to operate effectively.

The other choices do not contribute to safe driving practices. Speeding up to prevent the truck from changing lanes could create a dangerous situation, potentially leading to a collision. Ignoring the signal disregards the truck driver's intentions and can cause confusion on the road. Cutting in front of the truck is particularly hazardous, as it may not provide sufficient stopping distance for the truck, increasing the risk of a crash. Thus, the best choice is to move to the adjacent lane, fostering a safer driving environment.
