What should you do if you find yourself in an emergency with no space to steer away from a crash?

In an emergency situation where you cannot steer away from a crash, using controlled braking is the appropriate action to take. Controlled braking helps to minimize the impact by allowing you to slow down your vehicle as much as possible before a collision occurs. This can lessen the force of the impact, potentially reducing the severity of injury and damage.

While switching off the engine, accelerating quickly, or signaling for help might seem like reasonable actions in some scenarios, they do not provide the critical immediate control over your vehicle in the way controlled braking does. For example, switching off the engine may lead to a loss of braking power in some vehicles, while accelerating could increase the severity of the crash by making your vehicle hit the obstacle or other vehicle with more force. Signaling for help would be important after the incident, but it does not address the immediate need to reduce speed to avoid a severe accident. Thus, utilizing controlled braking is the most effective response in this critical moment.
