The "humps in the road" sign, often known as a "road hump" or "speed hump" sign, indicates a traffic calming device on the road designed to reduce vehicle speeds. These humps are raised sections of the road surface that create a gentle incline and decline, encouraging drivers to slow down to maintain safety, especially in residential or accident-prone areas. The sign warns drivers to prepare for these speed-reducing humps ahead so as to adjust their speed accordingly and avoid damage to vehicles or discomfort to passengers.

Road Hump Characteristics

• Speed humps are rounded and span the width of the road.
• They typically reduce vehicle speeds to about 25-30 km/h (15-20 mph) over the hump.
• Designed to calm traffic flow and enhance safety, especially in neighborhoods.
• Signs usually include pavement markings and warning signals for visibility.

Purpose of the Sign

• Alert drivers to slow down due to upcoming humps.
• Enhance safety for pedestrians, cyclists, and other road users.
• Reduce accident risks and promote smoother traffic flow.

Thus, the "humps in the road" sign serves as an important warning for traffic calming measures implemented on the road ahead.
