San Dimas sees its share of everyday traffic — commuters merging onto SR-57 and SR-210, drivers cutting across Arrow Highway to reach the foothills or the fairgrounds. In the most recent year on record, the city logged 139 injury collisions and 204 people hurt, along with 3 traffic deaths. Numbers like that represent real people dealing with medical bills, missed work, and a lot of uncertainty about what comes next. LawProactive is a free service — we are not a law firm. We connect people who've been injured in San Dimas with an independent attorney who can look at what happened and explain your options under California law. Attorneys in our network work on contingency, meaning there's no fee unless you recover compensation. California generally gives you two years from the date of injury to file a claim, though claims against a government agency can require action in as little as six months, so it helps to move sooner rather than later. If a crash near SR-57, SR-210, or Arrow Highway has upended your routine, you don't have to sort through the legal side alone.
