LA traffic is a cliché for a reason — but the details matter more than the reputation, because when you leave and which freeway you take change the drive more here than almost anywhere. Here's how Los Angeles traffic actually behaves, and how to find the best time to leave for your route.
LA drivers lose 87 hours a year to traffic
According to the 2025 INRIX Global Traffic Scorecard, the average Los Angeles driver lost 87 hours to congestion in 2025, ranking LA 4th most congested in the United States — behind Chicago, New York and Philadelphia. One notable detail: LA was one of the few major metros where delays actually fell slightly year over year, but 87 hours is still more than two working weeks in traffic.
And the shape of the week matters here: Inrix analysis has measured LA's Friday afternoon commutes running roughly 44% longer than free-flow — enough to add about 13 minutes to a trip that would otherwise take 30.
When is LA traffic worst?
Mornings run roughly 6:30–9:30 a.m. and evenings roughly 3:30–7:30 p.m. — LA's rush hours are among the most extended in the country, and Friday afternoon is reliably the worst window of the week. By freeway:
- The 405 — the Sepulveda Pass between the Westside and the Valley is the signature crawl, heavy in both directions at both peaks.
- The 10 — the Santa Monica Freeway east-west across the basin backs up hard toward downtown in the morning and toward the coast in the evening.
- The 101 — through Hollywood and downtown, slow well beyond the nominal windows.
- The 5 — heavy through downtown and the corridor south toward Orange County.
- The 110 — downtown interchanges back up early; the four-level interchange ripples onto everything it touches.
The simple move: shift off the peak
Leaving just before or just after the busiest window clears a surprising share of the delay — LA's freeways genuinely thin out on either side of the peak, even if they never fully empty. Against an 87-hour annual average, a consistent 15–30 minute shift is one of the few free wins available.
Three LA-specific things that move the peak
- The Friday effect. Friday afternoons run far heavier than the rest of the week — if any trip is flexible, Friday 3–7 p.m. is the window to avoid.
- SigAlerts. A single incident on the 405 or the 10 can add more time than the rush itself. Checking your route before leaving matters precisely because LA delays are incident-driven as much as volume-driven.
- Rain. It rains rarely enough here that when it does, speeds collapse — a wet morning is a leave-early morning. See how weather affects traffic.
Why your best time is route-specific
The 405 doesn't peak like the 10, a Tuesday isn't a Friday, and an incident rewrites everything. Citywide advice smooths over exactly the differences that decide your drive. (Nationally, the worst day of the week varies by city too.)
Find the best time to leave for your LA route
Google Maps and Waze show live traffic and turn-by-turn once you are already on the road. BoardSpy is the leave-time app: it checks your saved LA route before you leave, recommends when to go, sends traffic and weather alerts, tracks delay and on-time stats (including best and worst days), and factors in weather along the way. When you set off, it opens your map app for turn-by-turn. For how routing apps differ from departure-timing tools, see best app to avoid traffic and Google Maps commute alternatives.

Frequently asked questions
What is the best time to leave to avoid traffic in LA?
It depends heavily on which freeway you use — the 405, the 10 and the 101 peak at different times, and the gap between the best and worst departure on the same route is around 30 minutes. Friday afternoons are the exception across all of them.
When is LA rush hour?
Roughly 6:30–9:30 a.m. and 3:30–7:30 p.m. — among the longest rush hours in the country, with Friday afternoon the heaviest window of the week.
How bad is LA traffic compared to other cities?
In the 2025 INRIX scorecard, LA ranked 4th most congested in the US, with the average driver losing 87 hours a year — though delays actually fell slightly year over year, one of the few major metros to improve.
Is Friday traffic really worse in LA?
Yes. Inrix analysis measured LA's Friday afternoon commutes at roughly 44% longer than free-flow conditions — about 13 extra minutes on a 30-minute trip, the worst regular window of the week.
What is the worst freeway in LA?
The 405 through the Sepulveda Pass is the most notorious, with the 10, the 101, the 5 and the 110 interchanges all among the heaviest at peak. Which is worst for you depends on your route and direction.
How do I find the best time to leave for my LA commute?
Use a leave-time commute app that reads your actual route — not only a live map. BoardSpy recommends when to leave for your LA commute route, sends pre-departure traffic and weather alerts, and tracks on-time performance and best and worst traffic days. Download it at https://boardspy.site/apps/.
