Getting hurt in a car accident can change your life — and not in a good way. The pain and suffering you now carry because someone else was not doing their job on the road is unacceptable. Our Boise car accident attorneys are here to help you get through this difficult time. Please do not hesitate to call us and set up a free first consultation.

Car accidents are the leading cause of serious personal injury in Ada County and across the Treasure Valley. The Idaho Transportation Department consistently records more than 20,000 reportable crashes in Idaho every year, with Ada County and Canyon County accounting for a disproportionate share of those crashes due to the region’s rapid population growth and the volume of traffic on I-84, Eagle Road, Chinden Boulevard, Fairview Avenue, and the expanding network of Meridian and Nampa city streets. Behind those numbers are real people — Boise residents, Meridian families, Nampa workers, and people from every corner of the Treasure Valley whose lives were changed in an instant by someone else’s negligence.

Car Accident Cases We Handle Throughout the Treasure Valley and Idaho

Every car accident is different. The crash type, the injuries, the insurance coverage available, and the parties responsible all shape how the case is built and what it is ultimately worth. Below are the specific practice areas we handle across Boise, Meridian, Nampa, Eagle, Caldwell, and statewide. Each linked page covers the Idaho law, the evidence strategies, and the insurance issues specific to that crash type in depth.

Hit and Run Accidents in Idaho

A hit-and-run crash leaves you with injuries, a damaged vehicle, and one infuriating question — who is going to pay? In Idaho, the answer usually lives in your own uninsured motorist (UM) coverage under Idaho Code Section 41-2502. Idaho requires every auto policy to include UM coverage unless you rejected it in writing, meaning most Idaho drivers have more protection than they realize. We help victims in Boise, Nampa, and across the Treasure Valley recover through UM coverage, MedPay, and resident relative policies even when the at-fault driver is never identified. If impairment is suspected, the 180-day dram shop notice deadline under Idaho Code Section 23-808 makes calling us immediately critical.

Rear-End Collisions in Boise and the Treasure Valley

Rear-end crashes are the most common collision type on Idaho roads — concentrated on I-84, Eagle Road, Chinden Boulevard, Fairview Avenue, and the Meridian-to-Nampa corridor — and the most misunderstood by insurance companies. Idaho Code Section 49-638 creates a strong presumption that the rear driver was at fault. Modern bumpers protect the vehicle, not the person inside it, and low property damage does not mean a low-value injury claim. We handle rear-end cases from minor-impact soft-tissue claims to herniated disc and traumatic brain injury cases, including chain-reaction pileups on I-84 and distracted driving crashes where cell phone records under Idaho Code Section 49-1401A are a key piece of evidence.

Head-On Collisions in Idaho

Head-on collisions are Idaho’s deadliest crash type relative to their frequency. A crash at 45 mph in each direction delivers the equivalent of a 90 mph impact. These cases frequently involve catastrophic injuries, wrongful death claims under Idaho Code Section 5-311, and — when a drunk driver caused the crash — an exception to Idaho’s non-economic damages cap under Idaho Code Section 6-1603. The rural two-lane corridors where we see these crashes most often include SH-55 north of Eagle toward McCall, SH-21 toward Idaho City, US-95 through central Idaho, and US-20 through Camas Prairie.

T-Bone and Intersection Accidents in Boise

Side-impact crashes give the occupant roughly six to eight inches of crumple zone — compared to three to four feet in a frontal collision. The injuries reflect that: pelvic fractures, traumatic brain injury, spinal cord damage. Idaho Code Section 49-640 governs right-of-way at intersections, and violations are negligence per se. We know Ada County’s highest-crash intersections — Eagle Road at Chinden, Eagle Road at Fairview, Curtis Road at Fairview, Overland at Five Mile — and we know how to pull ACHD signal timing records before they overwrite. When a signal design or flashing yellow arrow issue contributed to the crash, we pursue the government entity claim under Idaho’s Tort Claims Act.

Rollover Accidents in Idaho

Rollover crashes are almost never caused by a single factor. Driver error, a tire failure, a soft shoulder on a rural Idaho highway, or a vehicle stability defect can all contribute — and each may represent a separate defendant. When a rollover involves a vehicle defect, preserving the vehicle before the insurance company disposes of it is the single most important action to take. We handle rollovers involving driver negligence, manufacturer product liability, and government roadway maintenance failures — including highway edge drop-offs on I-84, US-95, and SH-55 that constitute tripping events under ITD’s own engineering data.

Uninsured and Underinsured Motorist Accidents

Roughly one in eight Idaho drivers operates without liability insurance. Even insured drivers frequently carry only Idaho’s minimum $25,000 per-person limits — a number a single Boise emergency room visit can exhaust before discharge. Idaho Code Section 41-2502 requires every Idaho auto policy to include UM/UIM coverage unless you signed a written rejection. Most Idaho drivers have never signed that form, which means they have more protection than they know. We read every household policy — not just the declarations page — to find every dollar of available coverage, and we fight insurers who try to use anti-stacking provisions or illusory coverage arguments to minimize your recovery.

Speeding Accidents in the Treasure Valley

Speed is a contributing factor in roughly one-third of Idaho traffic fatalities according to ITD data. Kinetic energy increases with the square of velocity — a vehicle at 40 mph carries nearly 2.5 times the destructive energy of the same vehicle at 25 mph. Idaho Code Section 49-654’s basic speed rule applies even when a driver is below the posted limit — if conditions required slower travel, excessive speed is still a violation. The Treasure Valley corridors where we see the most serious speeding crashes are Eagle Road, Chinden Boulevard east of Eagle, I-84 between the Franklin and Meridian exits, and State Street through Garden City. We pursue event data recorder downloads and accident reconstruction to prove speed after the crash, and we pursue punitive damages under Idaho Code Section 6-1604 when extreme speeding supports it.

Dangerous Roads and Intersections in Idaho

Some Idaho roads produce crashes year after year at the same locations because road design, signal timing, or maintenance creates conditions that make crashes predictable. When ITD, ACHD, a city, or a county knew about a chronic hazard and failed to act, that agency may share liability. Ada County’s most persistent crash-location intersections include Eagle Road at Chinden, Eagle Road at Fairview, Curtis Road at Fairview, and Overland at Five Mile. Idaho Tort Claims Act claims under Idaho Code Section 6-901 require written notice within 180 days of the crash — a deadline we file immediately in every case where a public entity may be involved.

Intersection Accidents in Boise and Meridian

Intersections are where the largest share of serious Treasure Valley crashes occur and where evidence disappears fastest. Signal timing data rolls over within days. Intersection camera footage overwrites on 7- to 30-day cycles. We handle every intersection crash type — red-light running, left-turn-across-path failures, stop-sign violations, signal malfunctions, and roundabout entry crashes. We send preservation letters to ACHD, ITD, and nearby businesses the same day we are retained. If you were hit at an intersection in Boise, Meridian, Nampa, Eagle, or anywhere in Ada County, do not wait.

Road Rage and Aggressive Driving Accidents

Road rage cases are legally different from ordinary car accidents. When a driver deliberately uses a vehicle to harm or intimidate, the claim can include intentional tort claims alongside standard negligence, punitive damages under Idaho Code Section 6-1604, and an exception to Idaho’s non-economic damages cap. The other driver’s liability insurer may deny coverage for intentional acts — which is why we immediately analyze the injured party’s own UM/UIM coverage as the primary recovery path. Road rage incidents in the Treasure Valley concentrate on I-84 during peak commute hours and on Eagle Road in both directions during morning and evening rush.

Parking Lot Accidents in Boise and the Treasure Valley

Low speed does not mean low injury. Hip fractures in older adults, traumatic brain injuries, and crushed feet are all documented outcomes of parking lot crashes at backing speed. These cases involve both driver negligence and — when the lot design or maintenance contributed — premises liability claims against the property owner. Commercial parking lot cameras typically overwrite on 7- to 30-day cycles. We move immediately on preservation. Parking lot DUI crashes also open dram shop claims against the establishment under Idaho Code Section 23-808, subject to 180-day written notice.

Work Zone and Construction Zone Accidents

Idaho doubles traffic fines in active work zones — a recognition that these environments create elevated crash risk. The Treasure Valley has been in near-continuous road construction for years, with active projects on I-84, Eagle Road, Chinden Boulevard, and throughout Meridian and Nampa. Work zone crash liability rarely belongs to the driver alone. The prime contractor, the traffic control subcontractor, and ITD or ACHD who approved the project can all share responsibility when a work zone fails to meet MUTCD standards. We pursue every defendant and serve the 180-day Tort Claims Act notice immediately in every work zone case involving a government entity.

Idaho Accident Report and Claim Guide

What you do in the first 72 hours after a crash shapes the insurance claim, the available evidence, and the ultimate value of your case. This guide covers Idaho’s SR-1 reporting requirement under Idaho Code Section 49-1305, the insurance contact sequence that protects your interests, why you should never give a recorded statement to the other driver’s insurer, and every critical deadline — including the two-year personal injury statute under Idaho Code Section 5-219, the 180-day government notice under Idaho Code Section 6-901, and the 180-day dram shop notice under Idaho Code Section 23-808.
