I-15 (with US-89)
Through Bountiful, US-89 rides on I-15 itself until the two split near Farmington. Commuter peaks and freight in both directions produce multi-car crashes where fault gets divided rather than simply assigned.

DAVIS COUNTY
Hurt on I-15, Legacy Parkway or the east bench? Free consultation, and no attorney fees unless we win.
Bountiful sits on a narrow bench between the Wasatch and the Great Salt Lake marshes, and traffic between Salt Lake City and north Davis County squeezes through it on I-15, Legacy Parkway and Main Street. Neighborhood streets then climb steeply up the east bench. For the streets with the most crashes in UDOT’s records, see Bountiful’s most dangerous roads.
Through Bountiful, US-89 rides on I-15 itself until the two split near Farmington. Commuter peaks and freight in both directions produce multi-car crashes where fault gets divided rather than simply assigned.
Since January 2020 the posted limit has been 65 mph and large semi-trucks are allowed, ending the old 55-mph, no-semis agreement. Faster traffic and heavy trucks on a dark, exit-sparse road beside the wetlands shape the crashes here.
400 North carries SR-106 from I-15's exit 317 into town before the route turns north on Main Street; 500 South is the other main link to the freeway. Left turns across traffic and busy shopping driveways are the usual collision.
The old highway alignment, now a two-lane street past shops and churches, with parked cars, people crossing and cross traffic at nearly every block. Sight lines and speed are usually what gets argued.
Steep, curving residential streets with little shoulder and road cyclists year-round. Braking distance on a grade, and how much room a driver gave a rider, decide these cases.
Agencies and deadlines
Bountiful City Police handle city streets, and the Highway Patrol usually handles I-15 and Legacy Parkway. When UDOT, UTA, Davis County or the city is involved, through a work zone, a signal or a public vehicle, notice is due within one year.
Utah's no-fault PIP on your own policy pays first: a minimum of $3,000 for medical care and 85% of gross lost wages capped at $250 a week, for up to 52 weeks. PIP in detail.
To pursue pain and suffering from the at-fault driver, Utah requires at least one of the following:
Meet one and the at-fault driver's insurer owes the whole claim; if its limits fall short, underinsured motorist coverage on your policy stacks on top rather than being offset. How that stacking works.
Utah Code § 78B-5-818 reduces what you recover by your own percentage of fault and bars recovery unless the other parties' combined fault is greater than yours.
On I-15 the argument is following distance when traffic stopped; on Legacy, speed and lane position at night; on the bench, speed through a curve. Early photos, dash and doorbell video, and witnesses keep your share down.
Deadlines to Know
Four years for most crash injuries; two years for a wrongful-death claim; one year to notify UDOT, Davis County or Bountiful City of a claim. Deadline guide.
I-15 through Bountiful and toward the Farmington split, including rear-end chains in the commuter peaks.
400 North, 500 South and Main Street, where left turns and shopping driveways meet steady traffic.
Bountiful Boulevard and the steep streets above town, with riders sharing narrow pavement.
Run-off-road and truck-involved collisions on the darker stretch beside the wetlands.
A fleeing or uninsured driver doesn't end the claim: your UM coverage may pay, and if the other car never touched you, you need clear and convincing proof beyond your own testimony that it existed. Hit-and-run steps.
If a Bountiful crash case is filed, it goes to Second District Court in Farmington (800 West State Street), the district court for Davis County. Most settle without that.
