If the vehicle suddenly turns off during driving, of course, don't panic at first, try to stabilize the car and don't hit the direction, turn on the double flash and brake slightly as appropriate. If it is a manual car, you can step on the clutch, hang the gear lever to the corresponding gear according to the vehicle speed, and then release the clutch to start the engine at the vehicle speed, which is similar to starting the engine with a big car, or you can restart the engine directly;
If it is an automatic car, first carefully shift the gear to neutral, and be careful not to shift to reverse gear (R gear) by mistake, otherwise the transmission will be damaged, and then restart the engine. Of course, you can also turn on the double jump light to park the vehicle and restart the engine. Then check the car condition according to the car condition. If you can't find out, you can only call the trailer for help.
