Cevap
1. Maintain two-handed control of the steering wheel to keep the vehicle in a straight path; 2. Stay off the service brake pedal completely; 3. Allow the vehicle to coast down and naturally bleed off momentum; 4. Ease smoothly onto the road shoulder and apply light brake pressure to complete the stop.
Standard CDL emergency procedure dictates that the driver must first secure steering control to counteract the severe pull of the failed tire, refrain completely from braking while moving fast, allow natural deceleration to reduce velocity, and finally guide the vehicle onto the shoulder with gentle braking once speed is under control.
