A loaded truck and a small car are approaching slowing traffic at similar speeds. What should the truck driver avoid assuming?
Correct answer: That the truck can stop in the same space as the car.
Heavy vehicles need substantial stopping room. Do not base the truck's margin on the behavior or stopping ability of the passenger car ahead.

Why should a truck driver buckle up even for a familiar short delivery trip?
Correct answer: The belt helps keep the driver in position to control the vehicle.
A seat belt helps retain the driver inside the vehicle and in a position to control it. Familiarity and trip length are not reasons to leave it unfastened.

An over-the-counter cold medicine makes a commercial driver feel dizzy. What is the safe choice?
Correct answer: Do not drive while the medication is impairing the driver.
Nonprescription medicine can still impair alertness or coordination. FMCSA advises against driving when medications cause drowsiness or dizziness.

Your truck must slow for a planned turn. How can you give following traffic useful warning?
Correct answer: Signal and begin the planned slowing early enough to be noticed.
Early signaling and braking give others time to recognize the intended movement. Do not rely on an abrupt change to communicate the plan.

Before taking a truck through a mountainous area, what information should be reviewed?
Correct answer: Weather, road conditions, detours and the route's demands.
Route planning should account for conditions and terrain. A realistic trip plan reduces the chance of being surprised by unsuitable roads or changing weather.

Using FMCSA's dry-condition following-distance guideline, what starting gap applies to a 60-foot combination traveling at 50 mph?
Correct answer: At least seven seconds.
The guideline adds one second when traveling over 40 mph. A 60-foot vehicle starts with six seconds for length, plus one for the higher speed; add further margin when conditions require it.

A dispatcher says the assigned truck was fine yesterday. What must its next driver establish before departure?
Correct answer: That the vehicle is in safe operating condition now.
A dispatcher or previous driver cannot replace the current driver's pre-trip responsibility. Inspect the vehicle and be satisfied that it is safe before operating it.

During pre-trip inspection, which part belongs with the service-brake checks on a combination vehicle?
Correct answer: The trailer brake connections.
The inspection list includes service brakes and their trailer connections. A combination's braking system is not limited to the tractor controls that the driver can see in the cab.

A pre-trip check reveals a crack in a truck's wheel rim. What should the driver do?
Correct answer: Have the unsafe wheel condition addressed before departure.
A cracked or broken wheel or rim is an unsafe condition identified by FMCSA. Tire inflation alone cannot establish the structural integrity of the wheel.

A commercial vehicle's steering wheel has a cracked spoke. What should the driver recognize?
Correct answer: This is a steering-system defect, not merely cosmetic damage.
The steering wheel must be secure and its spokes sound. A working horn or an apparently normal straight-ahead feel does not resolve a structural steering defect.

A driver checks only the cab brake pedal and ignores the rest of the brake system. Why is that incomplete?
Correct answer: Stopping depends on maintained components beyond the pedal.
Brake performance depends on the full system, including components such as actuators, linings and drums or rotors. A pedal check alone is not a complete brake inspection.

Road grime is hiding a truck's required rear lamps and reflectors. What should happen before departure?
Correct answer: Restore their visibility and check the lighting condition.
Required lamps and reflectors need to be visible within their applicable requirements. A truck's size does not replace functioning, visible lighting and conspicuity equipment.

An inspector has declared a CMV out of service for a defect. May it return to operation simply because the driver is late?
Correct answer: No; the out-of-service defects must be corrected first.
An out-of-service vehicle may not resume operation until the cited defects are corrected. Scheduling pressure and a driver change do not repair the vehicle or cancel the restriction.

A tiedown has visible damage that could weaken it. What is the appropriate decision before departure?
Correct answer: Replace or correct the deficient securement component.
Securement components must be capable of doing their job in their present condition. Damage that adversely affects performance is not cured by an old rating or by concealing it.

A truck's tiedowns pass outside its rub rails. Does that position alone establish a violation of the current federal tiedown-use rule?
Correct answer: No; the securement must still satisfy strength, attachment and protection requirements.
The former federal inboard-rub-rail clause was removed in 2006. Its absence does not approve an unsafe arrangement: tiedowns must remain secured, meet applicable strength requirements, and have edge protection where contact with cargo could cut or abrade them.

Why might an appropriate dunnage bag be used between cargo and a vehicle wall?
Correct answer: To fill a space and help restrain or protect the cargo.
Suitable dunnage can support, protect and help immobilize cargo. A bag must be suitable for its role; its presence does not repair other defective securement components.

An ordinary 4-foot crate weighs 900 pounds and is not blocked against forward movement. Under the general count rule, what is the minimum number of tiedowns?
Correct answer: One, provided the other securement requirements are also met.
An unblocked ordinary article no longer than five feet and no heavier than 1,100 pounds has a one-tiedown minimum under this rule. That count does not waive working-load-limit or adequate-restraint requirements.

An ordinary 21-foot article has no forward blocking and is not subject to a special securement method. What is the general minimum tiedown count?
Correct answer: Four.
The rule uses two tiedowns for the first ten feet, then one for each further ten feet or part of ten feet. The remaining eleven feet requires two more, for a total of four.

A driver is loading cargo covered by a more detailed commodity-specific securement rule. Is compliance with the general rule alone enough?
Correct answer: No; applicable additional commodity-specific requirements also matter.
Commodity-specific provisions can prescribe extra or more detailed securement. Check the requirements for the actual cargo rather than assuming a general count settles the entire question.

A round load is supported by wedges that could shake loose on the road. What must be corrected?
Correct answer: Secure the rolling restraints so they cannot unintentionally release.
Rolling restraints must keep working throughout transport. A restraint that can become loose or unfastened does not reliably prevent the load from rolling.
