Question

What is the purpose of a device used to stop runaway vehicles?

1) To prevent injury to drivers, passengers, and vehicles
2) To control traffic flow
3) To provide emergency assistance
4) To enforce traffic laws

Answer 1

Devices used to stop runaway vehicles aim to prevent injuries and damage by controlling traffic flow, which can include traffic signals at intersections where there is a history of accidents.

Step-by-step explanation:

The purpose of a device used to stop runaway vehicles is primarily to prevent injury to drivers, passengers, and bystanders, and to minimize damage to vehicles and other property. These devices are part of broader traffic control measures, which can include traffic signals, cameras, and emergency assistance systems designed to manage the flow of traffic and enhance safety.

For example, the installation of a traffic signal at a busy intersection is often motivated by excessive speeding and a high incidence of accidents, which can harm pedestrians and drivers. In some cases, such as tollbooths, wires on the pavement serve both to detect approaching vehicles and to control traffic flow for toll collection purposes.
