What Defines a Commercial Vehicle in Arizona?

Arizona law classifies commercial vehicles as those used for business purposes, including transporting goods or passengers. This category encompasses:

• Large trucks and semi-trailers

• Delivery vans

• Buses (school, transit, charter)

• Taxis and rideshare vehicles used commercially

The regulations governing commercial vehicles are stricter than those for private cars, reflecting their increased potential for harm.

Arizona’s DUI Laws for Commercial Drivers

Commercial drivers are held to higher standards when it comes to DUI:

• The legal blood alcohol concentration (BAC) limit is 0.04% for commercial drivers, half the standard 0.08% for regular drivers.

• Arizona enforces strict penalties for DUI in commercial vehicles, including license suspension, fines, and criminal charges.

• Commercial drivers may also face federal regulations and employer disciplinary action.

Liability in DUI Commercial Vehicle Crashes

When a commercial vehicle driver causes a DUI crash, liability generally falls on:

• The driver, for their negligent and illegal conduct.

• The employer or trucking company, if the driver was acting within the scope of employment.

• The vehicle owner, if different from the employer or driver.

Because commercial vehicles often carry insurance policies with higher liability limits, victims may be able to recover greater compensation.

Damages and Compensation

Victims of DUI crashes involving commercial vehicles may pursue damages for:

• Medical expenses

• Lost wages and future earning capacity

• Pain and suffering

• Property damage

• Punitive damages, if gross negligence is proven

Given the complexity and severity of such claims, expert legal guidance is critical.
