Are arterial road accidents treated differently than freeway accidents?
Procedurally, city PD vs CHP handles the report. Legally, the same negligence standards apply. City roads can also trigger public entity liability claims for dangerous conditions.
What if a pothole or broken road caused my accident?
Road defect claims against public entities are possible but have a 6-month Government Tort Claim filing deadline. Call us immediately.
Does Gonzales Law handle accidents on surface streets?
Yes — the majority of our cases involve city streets, not just freeways. We know Inland Empire roads at the neighborhood level.
What makes Baseline Road so dangerous?
Length (spans multiple cities), high speed limits for an arterial (45-50 mph), commercial driveways creating unexpected stop patterns, and long signal spacing.
