Difficulty: EasySpace to Cross or Enter Traffic

A commercial driver operating a loaded combination vehicle is stopped at an intersection preparing to enter a busy highway. In what chronological sequence should the driver perform the steps required to safely enter traffic?

  1. 1Come to a complete stop and visually scan approaching traffic from both directions.
  2. 2Identify a traffic gap large enough to accommodate the vehicle's length and slow acceleration.
  3. 3Accelerate smoothly into the travel lane without forcing approaching vehicles to brake.
  4. 4Increase speed to match the prevailing traffic flow while monitoring rear mirrors.

Answer

The correct procedural order begins with stopping and scanning all traffic directions, followed by evaluating a gap large enough for the vehicle's length and weight, accelerating smoothly into the open lane, and finally reaching the speed of traffic while checking mirrors.
Safely entering a roadway requires establishing a full stop and assessing traffic first, verifying a sufficiently large opening for the heavy vehicle's length and acceleration rate, pulling smoothly into the lane, and then matching roadway speed.

Step-by-Step Solution

1
Scan oncoming traffic from a full stop.
Driver gains complete visual awareness of approaching vehicle speeds and distances.
Commercial vehicles require full visibility before any entry maneuver begins.
2
Select an appropriate gap in the traffic stream.
Adequate time and distance are confirmed to clear the lane safely without conflict.
Large vehicles take significantly longer to accelerate and clear lanes than passenger cars.
3
Initiate smooth entry into the designated lane.
Vehicle enters the roadway cleanly without interrupting existing traffic flow.
Entering smoothly prevents cargo shifts while occupying the necessary road space.
4
Accelerate to cruising speed and monitor surrounding space.
The vehicle integrates seamlessly into the traffic stream with safe spacing.
Matching prevailing speed minimizes closing speed hazards from trailing vehicles.

Key Concept

Entering and crossing traffic in a heavy vehicle requires recognizing the time and space needed for slow acceleration and vehicle length before entering the roadway.
