The road-test route lacks a situation the examiner needs to assess. What may the examiner ask you to do?
Correct answer: Explain what you would do in a simulated version of that situation.
Section 13 allows an examiner to assess an unavailable traffic situation through simulation and explanation. Follow the examiner's directions and continue to obey signs, signals and traffic laws.

When directed to turn during the road test, which preparation is appropriate?
Correct answer: Check traffic, signal and safely position for the turn.
The handbook calls for traffic checks, signaling, safe lane position and smooth speed adjustment before turning. Prepare early enough to maintain control rather than making a rushed movement.

You must stop while waiting to make a turn in the road test. How should the front wheels be positioned?
Correct answer: Aimed straight ahead while waiting.
Section 13 specifies straight front wheels while stopped before the turn. Keep the vehicle from rolling and recheck traffic before starting the maneuver.

During a turn, why keep checking the mirror on the inside of the turn?
Correct answer: To ensure the vehicle clears objects along its inside path.
The inside path of a long vehicle can approach curbs or objects. The handbook requires checking that the vehicle does not strike anything inside the turn while also monitoring surrounding traffic.

A stop is required at an intersection with a marked stop line. What should the road-test stop demonstrate?
Correct answer: A complete controlled stop behind the line, without rolling.
Section 13 evaluates a smooth complete stop at the required position, a safe gap behind vehicles ahead and no forward or backward roll. Vehicle size does not remove the need to respect the stop line.

The examiner requests a lane change on a multi-lane road. What should precede lateral movement?
Correct answer: Traffic checks and the proper signal, followed by a safe gap.
Make the necessary traffic checks, signal and change lanes smoothly when safe. An examiner's request does not make an unsafe lane change acceptable.

What should an expressway entrance demonstrate during the road test?
Correct answer: Traffic checks, signaling and a smooth merge into the proper lane.
The road-test guidance emphasizes a checked, signaled and smooth merge. Once in the traffic stream, maintain suitable lane position, spacing and speed while continuing traffic checks.

After traffic checks and signaling for an expressway exit, where does the handbook describe smooth deceleration?
Correct answer: In the exit lane, continuing within the ramp's lane markings.
Section 13 describes smooth deceleration in the exit lane and continued controlled slowing on the ramp. Stay within its markings and maintain adequate space around the vehicle.

For the road-test roadside stop, which final location is appropriate?
Correct answer: Parallel to the shoulder and safely clear of the traffic flow.
Check traffic and signal right before a controlled stop. The vehicle should finish parallel and out of traffic without blocking driveways, hydrants, intersections or signs.

After the road-test roadside stop is safely completed, what sequence does the handbook describe?
Correct answer: Cancel the turn signal, use hazards, set the parking brake and select neutral or park.
Section 13 describes canceling the turn signal, activating four-way flashers, applying the parking brake and selecting neutral or park. Secure the vehicle rather than relying on holding the pedals.

When instructed to resume from the roadside stop, what should you do before moving into traffic?
Correct answer: Check traffic and mirrors, switch off hazards and signal left.
Recheck traffic thoroughly, especially from the left, and use the left signal after turning off the hazards. When a safe gap permits, release the parking brake and pull forward before steering smoothly into the lane.

How should you prepare for a curve in the road test?
Correct answer: Reduce to a suitable speed before entering and keep the vehicle in its lane.
Section 13 calls for reducing speed before the curve so planned braking or shifting is not needed inside it. Continue traffic checks and lane control; respond safely if conditions change unexpectedly.

Once any part of your commercial vehicle is in a railroad crossing, what should you avoid?
Correct answer: Changing gears, stopping, passing or changing lanes in the crossing.
Prepare and select the appropriate gear before crossing. The handbook warns against stopping, shifting, passing or changing lanes while any part of the vehicle remains in the crossing; enter only when the whole vehicle can clear.

After passing an overpass or bridge, what might the examiner ask you to identify?
Correct answer: Its posted clearance or weight restriction.
The test may assess whether you noticed and understood a clearance, weight-limit or other traffic sign. Read applicable restrictions before reaching the structure, not just after the examiner asks.

For a test vehicle with an unsynchronized manual transmission, what shifting technique does Section 13 require?
Correct answer: Double-clutch when shifting, without revving or lugging the engine.
The handbook's double-clutch requirement applies to an unsynchronized manual transmission. Do not turn it into a rule for automatic vehicles; avoid riding the clutch or coasting with it depressed.

After completing a manual gear change during the road test, what should you do with your shifting hand?
Correct answer: Return it to the steering wheel.
Section 13 expects both hands on the steering wheel except when shifting, followed by returning the hand to the wheel. Maintain smooth steering and continue regular traffic and mirror checks.
