Final answer:
To augment the safety provided by Jersey barriers, additional precautions like traffic signals should be implemented to ensure vehicles slow down approaching these barriers, minimizing the risk of accidents.
Step-by-step explanation:
When rationale is similar to why tollbooths install wires that touch cars; it serves as a cue for drivers to slow down and be aware of upcoming stops or potential hazards. Similarly, model cause-and-effect paragraphs about installing traffic signals highlight the rise in accidents and potential loss of life as reasons for needing such precautions, underscoring the urgent need for safety measures in conjunction with those barriers.
If Jersey barriers are used with the expectation of stopping moving vehicles, an added precaution that should be used is a crash cushion or attenuator. Crash cushions are designed to absorb the impact energy of a vehicle, reducing the risk of injury to the driver and passengers. They are usually made of materials that can crush or deform upon impact, such as foam or steel barrels filled with sand. These crash cushions provide an additional layer of protection by absorbing the kinetic energy of the vehicle, thereby minimizing the chances of severe damage to the barrier and increasing the likelihood of stopping the vehicle safely.
