We hear this question a lot. Idaho operates under a comparative negligence law.
This means that even if you were partially responsible for the incident, you may still be able to recover compensation, as long as your percentage of fault is 49.9% or less. However, your final financial recovery will be reduced by your exact percentage of fault. Because insurance companies will aggressively try to shift the blame to you to save money, it is vital to have an experienced injury lawyer refute those claims. Let us review your accident for free.

Did you know that posting on social media after a car wreck or injury can severely damage your legal claim? Insurance adjusters are professional negotiators, and one of their favorite tricks is snooping through an accident victim's public profiles.
A seemingly innocent photo of you smiling at a family dinner or a status update saying "I'm doing okay!" can be taken completely out of context to argue that your injuries aren't severe.
Our advice: If you are involved in an active personal injury claim, tighten your privacy settings, avoid posting about the incident, and ask friends not to tag you.

October brings beautiful fall colors to Idaho, but it also brings unique driving hazards. Shorter days mean blinding morning sun glare and increased wildlife activity during peak commute hours.
Stay safe on the road this month with these tips:
☀️ Keep a pair of polarized sunglasses in your vehicle.
🍁 Slow down on tree-covered roads where fallen leaves can make asphalt as slippery as ice.
🦌 Watch the shoulders for deer active during dawn and dusk.
