Vehicles displaying the "slow-moving vehicle" sign cannot exceed what speed?

Vehicles displaying the "slow-moving vehicle" sign are designed to warn other road users that they travel at lower speeds to ensure safety on the roads. The correct maximum speed for these vehicles is 25 mph (40 kph). This speed limit is enforced to prevent these vehicles from creating hazards, as they could disrupt the flow of traffic if they were to travel faster than this speed. Maintaining a maximum of 25 mph helps protect both the slow-moving vehicles and other drivers by allowing a clear understanding of what to expect on the road. The presence of the sign serves as an alert, so other drivers can adjust their speed and positioning accordingly.
