Step 3 · Interview How to interview for each commercial trucking role.
Everyone who applies will claim the experience. These are the questions that test it, the signals that separate a strong candidate from a plausible one, and the mistake each seat invites.
CDL-A Truck Driver
BLS 10th to 90th percentile Operates combination vehicles - tractor-trailer, flatbed, tanker, lowboy - on regional or over-the-road runs: pre-trip and post-trip inspections, load securement, hours of service compliance on an electronic log, and customer delivery conduct. On construction and trades work the load is often equipment or material to a job site.
Questions that find out
- Walk me through securing a piece of equipment on a flatbed.
- You are approaching your hours limit and the receiver is running late. What do you do?
- What do you check on a pre-trip that drivers most often skip?
What a strong candidate shows
- Clean MVR and a stable work history, with gaps explained rather than hidden
- Endorsements stated - tanker, hazmat, doubles - with current medical card
- Load securement described specifically for the trailer type they actually run
The mistake this seat invites. Hiring on licence class alone. Insurability, MVR and endorsement fit decide whether the driver can actually run the work, and that is checked before the interview, not after.
CDL-B Truck Driver
BLS 10th to 90th percentile Operates straight trucks and single-unit vehicles: service and delivery trucks, dump trucks, boom and crane trucks, vacuum and water trucks. On trades work the driver is usually also operating the equipment on the truck and working with the crew at the site.
Questions that find out
- What equipment have you operated from the truck, and what certifications go with it?
- How do you set up and level a boom truck on a sloped site?
- What is on your pre-trip for a dump truck that is not on a straight truck?
What a strong candidate shows
- Equipment operation on the truck described as part of the job, because it usually is
- Endorsements and any crane or equipment certifications stated with the licence
- Comfortable with the customer-facing and crew-facing side of a service truck
The mistake this seat invites. Treating the seat as a lower rung of CDL-A. On trades work the value is the equipment operation and the site conduct, not the driving.
Every role in every trade is in the interview question bank.
