Emergency Handling and Accident Response (紧急情况避险与事故处置)

This domain tests the first ten seconds of a failure or a crash. Questions are graded on the order of actions and on not making a bad situation worse: the right answer usually starts with control of the vehicle and ends with warning other traffic.

Vehicle failures

  • Blowout: grip the wheel with both hands, release the accelerator, hold the car straight, and brake gently only after speed has dropped. Never stamp on the brake or yank the wheel.
  • Brake failure: pump the pedal once, downshift progressively (抢挡) to use engine braking, then apply the parking brake gradually. If speed is still rising, use an uphill grade, a run-off area, or scrub along a barrier.
  • Steering failure: stop accelerating, brake gently to avoid a spin, switch on hazard lights.
  • Skid: for a rear-wheel skid, steer into the skid; for a front-wheel skid, straighten the wheel and ease off the accelerator.
  • Water: do not force the door open at once. Wait for the cabin to fill until pressures equalise, or break a side window with the safety hammer - laminated windscreens will not shatter.
  • Fire: stop, switch off the engine, isolate the battery, aim the extinguisher at the base of the flames, and open the bonnet only a crack.

Post-crash sequence

Stop, hazard lights on, warning triangle (50–100 m behind on ordinary roads; 150 m behind on the expressway), casualties first, then call 122 and 120, protect the scene, and move everyone behind the guardrail facing oncoming traffic. Any injury or fatality must be reported - it cannot be settled privately.

Worked example

A front-tyre blowout at 100 km/h on the expressway. Correct order: grip the wheel, ease off the accelerator, keep the car straight, let speed bleed off, gentle braking, hazard lights, pull onto the hard shoulder, triangle at 150 m, occupants behind the barrier. Options beginning with brake hard or swerve to the shoulder immediately are the designed traps.

Traps

  • Fully opening the bonnet to fight an engine fire.
  • Moving a suspected spinal injury to make them comfortable instead of controlling bleeding.
  • Placing the triangle directly behind the bumper, or standing behind the car while placing it.
