A new driver does not know how the truck should feel
Alignment problems are usually reported by drivers. A driver who has run the same truck for a year knows exactly how it tracks, and notices when that changes.
A fleet with driver turnover loses that. A new driver climbs into a truck that pulls slightly and assumes that is how this truck drives. They correct for it without thinking, every mile, and report nothing, because there is nothing to compare it with. Meanwhile the steer tires wear and the fuel goes on what is effectively a slight, permanent turn.
Give every driver a baseline
The fix is to record what a truck should feel like, so the knowledge belongs to the fleet rather than to whoever happens to drive it.
After every alignment, note the result. A straight-ahead steering wheel and no pull on a level road is the baseline. Put it in the unit file.
Ask new drivers a specific question. In their first week, on a straight and level stretch, does the truck hold its line with a light hand on the wheel, and does the steering wheel sit straight? A general "any problems?" gets a no. A specific question gets an answer.
Treat a reported pull as a measurement request. A driver saying the truck pulls is a reason to measure it, whoever the driver is.
A truck that pulls with one driver and not another is still worth measuring. Load, the trailer and how each driver describes things all vary, and the measurement settles it.
At the same visit
A trailer out of square pushes the tractor off line, so ask about trailer alignment too. A vibration rather than a pull is more often balancing. The national heavy-duty truck alignment page covers when to align.
