Question

Difficulty: MediumEmergency Vehicles, School Buses, and Work Zones

Arrange the following steps in the correct chronological order that a driver should follow when encountering an advance warning sign indicating an upcoming highway work zone lane closure.

  1. 1Read the advance warning signs to identify which lane will be closed ahead.
  2. 2Check mirrors and blind spots to locate suitable traffic gaps in the open lane.
  3. 3Activate turn signals and reduce vehicle speed to match the posted work zone speed limit.
  4. 4Merge smoothly into the open lane well before reaching the lane closure cones or taper.

Answer

The correct procedure sequence is: 1. Read advance warning signs to identify the closed lane; 2. Check mirrors and blind spots to locate traffic gaps; 3. Activate turn signals and slow down to the work zone speed limit; 4. Merge smoothly into the continuing lane well before the taper.
Safe work zone driving requires early planning. The process begins by reading advance warning signs to identify the lane closure. Next, checking mirrors identifies safe gaps in traffic. The driver then signals intent while reducing speed to the posted work zone limit, finishing by merging smoothly into the open lane well ahead of the construction taper.

Step-by-Step Solution

1
Scan and observe advance warning signs ahead.
The driver identifies the upcoming work zone and determines which lane is ending.
Early observation provides sufficient distance and time to plan appropriate driving adjustments.
2
Check rearview mirrors, side mirrors, and blind spots.
The driver locates an open gap in the continuing lane traffic.
Checking surroundings ensures that moving over will not cause a collision with adjacent vehicles.
3
Turn on the direction signal and slow down to the posted work zone speed limit.
The vehicle communicates intent to other drivers and reduces kinetic energy.
Lower speeds protect road workers and reduce severe collision risks in tight merge areas.
4
Complete the lane change into the open lane prior to the barrier taper.
The vehicle safely joins traffic flow in the continuing lane.
Early merging avoids traffic bottlenecks and dangerous hard braking near construction zones.
