- Brake failure response
- Downshift, apply the parking brake gradually, use engine braking, and look for an escape ramp or safe runoff area to stop the vehicle.
- Blowout response
- Hold the steering wheel firmly, ease off the accelerator, avoid hard braking, and steer to a safe stop away from traffic before setting out warning devices.
- Passenger carrier BAC limit
- Drivers of passenger carrier vehicles are subject to a 0.04% BAC limit; a CDL holder convicted of DUI is disqualified for one year, or three years with hazmat.
