Florida CDL — General Knowledge: Parking & Stopping Practice Test

Question 1

You have stopped just past a crest where drivers cannot see you until they are nearly on top of you. How does that change where the farthest warning device goes?

Accepted Answer

Carry it farther back down the road, past the crest, so traffic is warned well before it reaches you — A hill or a curve that blocks the view swallows the usual spacing. Walk the farthest device back beyond the obstruction so that approaching traffic gets a warning from at least 500 feet away.

Answer

Set it closer to the bumper so that nobody can miss it

Answer

Leave it packed away and rely on the flashers instead

Answer

Place it on the opposite shoulder of the road

Question 2

Where possible, how should a driver position a large vehicle when parking it?

Accepted Answer

So that leaving the space can be done by pulling forward — Backing is the most dangerous thing a large vehicle does, because so much of the path behind is hidden. Picking a spot you can drive straight out of removes that risk before it arises.

Answer

Backed in tight against a wall to save room

Answer

Angled so the trailer blocks the lane behind it

Answer

Wherever the walk to the building is shortest

Question 3

Your truck is disabled on the shoulder of a highway. How soon must the emergency warning devices be out on the ground?

Accepted Answer

Within ten minutes of stopping — Ten minutes is the outer limit for getting the devices placed, and sooner is better. Flashers alone are not enough, because a following driver can read taillights as a vehicle that is still moving.

Answer

Only if the stop is going to last more than an hour

Answer

Before you leave the cab for any reason

Answer

Within thirty minutes of stopping

Question 4

A transit coach has an interlock that applies the brakes whenever the rear door is opened. May the driver lean on it instead of the parking brake?

Accepted Answer

No, it is a passenger safety device and not a substitute for the parking brake — The interlock holds the throttle at idle and keeps the brakes on while riders board, then lets go once the door shuts. Securing a parked coach remains the parking brake's job.

Answer

Yes, as long as the rear door is left standing open

Answer

Yes, but only on ground that is level

Answer

Yes, whenever the engine is left running

Question 5

You have to stop your commercial vehicle on the shoulder of a highway. What should you do?

Accepted Answer

Pull as far off as possible, turn on flashers, and set out warning triangles — Get as far off the road as you can, turn on your four-way flashers, and set out your emergency warning devices (reflective triangles) so approaching drivers see you in time.

Answer

Leave the vehicle in the lane with the lights off

Answer

Stand behind the trailer to wave traffic around

Question 6

What is the safe way to carry a reflective warning triangle out along the roadway?

Accepted Answer

Held up between your body and the traffic coming toward you — The triangle doubles as your shield: approaching drivers pick up the reflector first and you second. Walking with it hidden leaves you invisible on a live shoulder.

Answer

Tucked under one arm out of sight of traffic

Answer

Held low at knee height so it does not dazzle drivers

Answer

Rolled inside the cab until the very last moment

Question 7

Whenever you park and leave a commercial vehicle, you should always:

Accepted Answer

Set the parking brake and secure it against rolling — Set the parking brake and, on a grade, chock the wheels or turn them toward the curb so the vehicle cannot roll. A heavy vehicle that rolls away can cause serious damage.

Answer

Leave it in neutral with the brake off

Answer

Leave the engine running at high idle

Question 8

What is the right technique for bringing a loaded commercial vehicle to a routine stop?

Accepted Answer

Build pedal pressure steadily so the vehicle settles into a smooth halt — How much pressure the stop needs depends on your speed and how quickly you have to be stopped, so meter it rather than stabbing at the pedal. With a manual gearbox, push the clutch in as the engine drops toward idle.

Answer

Press hard at first, then ease off near the end

Answer

Pump the pedal rapidly the whole way down

Answer

Let the parking brake do most of the slowing

Question 9

You reach a drawbridge that has no signal light and nobody on duty controlling traffic. What must you do?

Accepted Answer

Halt at least 50 feet short of the draw and make sure it is fully closed — With no one managing the crossing, the check falls to you. A green light or an attendant directing traffic removes the stop, though you still slow down and satisfy yourself that crossing is safe.

Answer

Cross without pausing if there is no boat in sight

Answer

Stop only when a warning bell is ringing

Answer

Sound the horn twice and then proceed

Question 10

A bus driver is required to stop at a railroad crossing. Where should the bus come to rest?

Accepted Answer

Somewhere in the band running from 15 to 50 feet ahead of the nearest rail — That window keeps the bus clear of a passing train yet close enough for the driver to see and hear down the line. Opening the front door can sharpen what the driver is able to hear.

Answer

With the front bumper right up against the near rail

Answer

Exactly one bus length short of the tracks

Answer

Anywhere the driver likes within 100 feet of the tracks
