Why This Question Matters for Colorado and Utah Residents

Company vehicles are a vital part of business operations across Colorado and Utah, but knowing when—and how—they’re covered can be confusing. Regulations, weather, and local risks make understanding policy details especially important in our region.

  • Employer and Employee Risk: With regional accident rates climbing (an 18% increase along I-25 since 2020), knowing who can use a company vehicle—and when—protects your business and your team from costly claims.
  • Local Claim Complexity: In Colorado, commercial auto liability judgments average $218,000, so policy clarity around personal use can make or break a business after a serious incident.
  • Regional Exposures: Our area is #2 in the nation for hail claims (42% of comprehensive claims), and theft rates are among the highest in the U.S.—so missteps on policy details mean significant financial exposure.

What Most People Get Wrong

Many business owners assume their commercial auto policy automatically covers any use of company vehicles, including nights, weekends, and family errands. In reality, most carriers require you to disclose personal use—and may exclude coverage if you haven’t notified them or secured the right endorsements.

Additionally, some policies limit coverage based on who is driving and the intended use. If an employee or owner uses a company vehicle for personal errands without proper coverage, claims could be denied.

The Complete Picture

Commercial auto insurance can extend to personal use, but only if your insurer is informed and your policy includes the right endorsements. Policies differ—some allow incidental personal use with prior approval, while others require you to specifically schedule additional drivers or purchase a special “personal use” endorsement. In Colorado and Utah, failing to disclose personal use is a common reason claims are denied or paid with restrictions. It’s critical to review your policy regularly, communicate any changes to how company vehicles are used, and confirm coverage for all drivers under all circumstances. Local agents, like FoCoIns, can ensure your policy is tailored to our region’s specific risks—hail, theft, high claim costs, and busy corridors like I-25 and I-15.

Making the Right Decision for Colorado and Utah Residents

Question 1: Have you clearly communicated all personal use scenarios to your agent?

Policy language can be vague. Make sure to:

  • List anyone who may use the vehicle outside business hours
  • Document occasional, regular, and family usage

Question 2: Does your policy include the right endorsements for your needs?

Ask your agent about options for personal use endorsements or non-business driver coverage. Examples in Colorado and Utah show that missing this step can lead to six-figure out-of-pocket exposure.

Question 3: Has your personal situation changed?

New employees, business growth, or drivers switching roles? Review coverage annually—especially with changing local risks (e.g., increased hail or rising theft rates on Colorado's Front Range and Utah’s urban corridors).

Real World Examples

Weekend Errands in Fort Collins: Jamie's Experience

Background: Jamie, a Fort Collins bakery owner, occasionally drives the company van for family errands on weekends.

Coverage: Their FoCoIns commercial auto policy includes a "personal use" endorsement covering all named owners and spouses.

Monthly Premium: $158/month ($1,896/year)

Total Claim Cost: $4,300 (vehicle repairs + rental during shop time)

Jamie's Cost: $500 deductible—policy paid the rest due to disclosed personal use.

"I’m so glad we updated our agent about using the van outside work. That quick conversation saved me thousands!"

Construction Crew's Family Use in Denver: Greg's Dilemma

Monthly Premium: $140/month ($1,680/year)

The Incident: One evening, Greg’s foreman is involved in a multi-car accident off I-25 while transporting his children (not work-related).

Total Claim Cost: $27,500 (injuries + property damage)

Greg's Cost: Entire claim denied for personal use not disclosed—Greg pays full amount out of pocket.

"We never thought a quick errand would create such a headache. Next time, every possible use will be on our policy."

Salt Lake City Service Van: Sara’s Proactive Coverage

Background: Sara runs a cleaning business in Salt Lake City, often letting her spouse use the company van for grocery runs in Park City when business is slow.

The Incident: Minor hailstorm in Park City results in $2,100 in roof and windshield damage while the van is parked for personal use.

Total Claim Cost: $2,100 (hail repair)

Sara’s Cost: $250 deductible—hail claim processed due to proper endorsement and full disclosure.

"FoCoIns made it easy to update our policy. When hail hit, we didn’t worry—it was all covered, even outside work hours."

Avoid These Common Mistakes

Mistake #1: Assuming Personal Use is Always Covered

What People Do: Business owners or employees use company vehicles for personal errands believing standard coverage applies automatically.

Why It Seems Logical: Many assume “commercial” means “all use,” especially when it’s their own vehicle.

The Real Cost: In Colorado and Utah, undisclosed personal use often leads to denied claims—costing $2,000 to $30,000+ out of pocket.

Smart Alternative: Always discuss all possible uses (including family or off-hours) with FoCoIns or your agent and add required endorsements to your policy.

Mistake #2: Not Listing All Drivers Who Might Use the Vehicle

What People Do: Only regular business drivers are on the policy; other employees or family members occasionally drive but aren’t disclosed.

Why It Seems Logical: To save on premium or because an occasional driver seems unimportant.

The Real Cost: Unlisted drivers often void coverage for accidents, with businesses in the region facing claim denials exceeding $20,000.

Smart Alternative: Proactively update your list of permitted drivers and ask about personal use endorsements. FoCoIns brokers make this process easy and clear.

Mistake #3: Relying on the State Minimum—Not Accounting for Personal Use Risk

What People Do: Choose low mandatory limits without considering the higher risks of personal, non-business use.

Why It Seems Logical: Minimizing upfront costs is appealing, especially for small businesses.

The Real Cost: State minimums (25/50/15) don’t cover serious claims—average at-fault accidents in the region ($218,000+) can bankrupt a business if coverage lapses due to personal use violations.

Smart Alternative: Secure high enough limits (recommended $500,000-$1M) and tailor your coverage for personal use scenarios to protect your company and your assets.
