While driving on a divided highway, you encounter an impenetrable blanket of fog that reduces forward visibility to near zero, making continued travel unsafe. Arrange the following emergency response steps in the correct chronological sequence from first to last.
- 1Gradually decrease speed and verify that low-beam headlights are active rather than high beams.
- 2Engage four-way hazard flashers to warn trailing traffic of your slowing commercial vehicle.
- 3Guide the vehicle completely off the highway into an authorized rest area or designated parking facility.
- 4Set the parking brake and turn off all standard driving lights while keeping emergency flashers operational.
Cevap
The proper sequential order is: first, gradually reduce speed and ensure low-beam headlights are active; second, engage four-way hazard flashers; third, guide the vehicle completely off the highway into an authorized rest stop or parking facility; and fourth, secure the vehicle and turn off standard driving lights while maintaining emergency flashers.
The correct sequence begins with immediate vehicle control by decelerating smoothly and using low beams to avoid blinding reflection. Next, hazard flashers alert trailing drivers to the speed drop. Then, the driver navigates off the road into a safe parking lot or rest stop rather than lingering on a dangerous shoulder. Finally, shutting off regular lights once parked prevents other drivers from tracking taillights into a collision.
