What is a speed bump?

1. A raised barrier designed to slow down traffic

2. A type of traffic signal

3. A road sign indicating speed limits

4. A legal requirement for street safety

The correct answer is: A raised barrier designed to slow down traffic

A speed bump serves as a raised barrier placed across roadways to effectively reduce the speed of vehicles. The design of speed bumps necessitates that drivers slow down when traversing them, which enhances safety for pedestrians, cyclists, and other road users. By compelling drivers to reduce their speed, speed bumps aim to minimize the risk of accidents in areas with high foot traffic, contribute to safer neighborhoods, and improve overall traffic calming measures. The other options do not accurately describe what a speed bump is. Traffic signals are electronic devices that regulate vehicle flow and are not physically raised barriers. Road signs that indicate speed limits provide information to drivers but do not physically alter the roadway to enforce those limits. Legal requirements for street safety can encompass a range of measures, but a speed bump specifically refers to a physical feature designed to control vehicle speed rather than a legal stipulation.
