CDL Driver interview questions and how to answer them

A CDL driver interview is mostly a background check with a conversation wrapped around it. The posting might be a Class B dump truck, a beverage route or a regional tractor job, and the manager wants to know one thing: will this person keep the truck, the load and the company's insurance out of trouble. Here's what they'll ask and what they're listening for.

12 questions8 minute read

Part 1

1.Which class of license do you hold, and which endorsements are on it?

Why they ask

The job is built around a specific truck. A Class B route job and a Class A regional job need different things, and a missing tanker or hazmat endorsement can rule out a big share of the freight in the building.

How to answer

  • State the class and every endorsement in plain words, not codes.
  • Say which endorsements you've actually used on the job versus only tested for.
  • Mention any restriction on the license, such as an air brake or automatic-only restriction, before they spot it.
  • Say whether you'd add an endorsement the job needs and how soon.

2.What trucks have you driven, and which of them are you actually comfortable in?

Why they ask

CDL work covers everything from a box truck with a lift gate to a tractor pulling a reefer. The manager wants to know how much training you'll need in their equipment.

How to answer

  • Name the vehicle types: straight truck, dump, tractor-trailer, tanker, bus.
  • Name the transmission: manual, automated manual or automatic.
  • Name the trailer or body: dry van, reefer, flatbed, roll-off, lift gate.
  • Be honest about the ones you've only driven at school.

3.Walk me through your in-cab air brake check.

Why they ask

It's the part of the inspection new drivers rush and experienced drivers skip. Hearing you describe it step by step tells them which kind you are.

How to answer

  • Describe the leak-down test with the engine off and brakes released, then applied.
  • Explain the low-air warning and when it should come on.
  • Describe fanning the brakes down until the spring brakes pop.
  • Mention the pressure build-up check and what you'd do if any step fails.
4.Tell me about everything on your driving record, including your personal vehicle.

Why they ask

They already have the MVR in front of them. This question is about whether you'll tell them the truth before they read it out to you.

How to answer

  • Name each ticket or accident, roughly when, and whether it was in a work truck or your own car.
  • Say which accidents were ruled preventable and what you changed afterward.
  • Keep it short and factual. No blaming the other driver.
  • If your record is clean, say so plainly and move on.
5.You're on a local route with a lift gate and a tight downtown dock. How do you plan the stop?

Why they ask

A lot of CDL jobs aren't highway jobs. They're city deliveries where the hard part is parking, backing and unloading without hitting a pole, a car or a person.

How to answer

  • Check the stop notes or call ahead for dock height, clearance and receiving hours.
  • Scout on foot before you back if you've never been there. Get out and look.
  • Use flashers, cones and a spotter if one's available.
  • Check the lift gate's rated load before you put a pallet jack on it.

Part 2

6.You find a problem on your pre-trip and the route's already late. What do you do?

Why they ask

They want to know whether schedule pressure will talk you into driving a truck you've just written up.

How to answer

  • Write it up on the DVIR (the driver vehicle inspection report) exactly as you found it.
  • Tell dispatch and the shop straight away so they can swap trucks or fix it.
  • Don't drive it if it's an out-of-service defect, whatever the schedule says.
  • Give an example of a time you held a truck and it was the right call.
7.How do you handle your hours of service when the day runs long?

Why they ask

Detention at a shipper, a breakdown or traffic can eat a day. They need to know you'll plan around the clock instead of fudging it.

How to answer

  • Say which ELD you've used and that you check your remaining time before each stop.
  • Explain when you'd call dispatch: early, while there's still time to re-plan.
  • Mention the short-haul exception if the job is local, and that you know when it no longer applies.
  • Never offer to run past your hours, even as a joke.
8.Tell me about a time a customer or receiver gave you a hard time.

Why they ask

On route and delivery work you're the only person from the company the customer ever sees. How you act on their dock is how they judge the company.

How to answer

  • Pick a real situation: refused freight, a long wait, a damaged pallet, a missing signature.
  • Say what you said to the customer and how you kept it calm.
  • Say how you documented it on the paperwork or scanner and who you called.
  • End with what happened to the account afterward.
9.What home time do you need, and how firm is it?

Why they ask

Mismatched home time is the most common reason new drivers quit. They'd rather lose you now than in your second month.

How to answer

  • Say exactly what you need: home daily, weekends, or out a set stretch and home a set stretch.
  • Say what you'd trade for it, like early starts or weekend shifts.
  • Ask how often the schedule actually matches what's in the posting.
10.What would you do if dispatch sent you a load you weren't qualified to haul?

Why they ask

This covers hazmat without the endorsement, a trailer heavier than your class allows, or passengers without a P endorsement. They need drivers who'll push back.

How to answer

  • Say you'd refuse the load and explain why to dispatch right away.
  • Mention checking the bill of lading for placards and weight before you hook or load.
  • Offer an alternative: another driver, a different truck, a swap later in the day.

Part 3

11.What happens if you're involved in an accident, even a minor one?

Why they ask

The first minutes after a crash decide how bad the claim gets. They want a driver who follows the company procedure instead of improvising.

How to answer

  • Secure the scene: flashers, triangles, check on people first.
  • Call the police if needed, then your safety department, before anyone else.
  • Take photos and don't admit fault or argue at the scene.
  • Know that a post-accident drug and alcohol test may follow.
12.Why are you leaving your current job?

Why they ask

Driving jobs have high turnover. They're checking whether you'll leave them for the same reason in a few months.

How to answer

  • Give one concrete reason: home time, equipment, the type of freight, a shorter commute.
  • Connect it to something this job actually offers.
  • Say nothing bad about your current dispatcher or manager, even if it's deserved.

Questions to ask them

Ask at least two. It shows you're picking them too.

  • What truck would I be assigned, and is it slip-seated or mine to keep?
  • How is the job paid: by the hour, by the mile, by the stop or by the load, and is detention paid?
  • What does the schedule actually look like in a normal week, start time included?
  • How long is training, and who rides with me?
  • Do drivers handle freight, like pallet jacks, hand trucks or tarping, or is it no-touch?
