LA traffic is a cliché for a reason, but the details matter more than the reputation — which freeway you take and which day you drive change the trip more here than almost anywhere. Here is what the data says, when the 405 and the 10 actually peak, and how to find the best time to leave for your route.
LA rush hour times
| Window | What to expect |
|---|---|
| Before 6:30 a.m. | Clear; best morning leave |
| 6:30–9:30 a.m. | Morning rush |
| 9:30 a.m.–3:30 p.m. | Midday lull; morning traffic has died down |
| 3:30–7:30 p.m. | Evening rush; Friday afternoons run about 44% longer than free-flow |
| After 7:30 p.m. | Evening peak has died down |
When does LA traffic die down?
Morning traffic dies down after about 9:30 a.m.; evening traffic after about 7:30 p.m.; Friday evenings run later.
Many California fire departments run a firefighter 48/96 schedule with a morning shift change, so both the drive in and the drive home two days later land inside the 6:30–9:30 a.m. window. On those mornings, leaving before the peak builds beats waiting for it to die down.
Use the table above for the full weekday windows. The midday lull is the reliable clear stretch; Friday is the day that stretches the evening peak past the usual 7:30 close.
LA drivers lose 87 hours a year to traffic
The INRIX 2025 Global Traffic Scorecard puts the average Los Angeles driver at 87 hours lost to congestion, ranking the metro 4th worst in the United States — behind only Chicago, New York and Philadelphia.
There is one unusual detail in that figure. LA was one of the few major American metros where delays fell in 2025, down about 1% from 88 hours the year before. Chicago rose 10%, Philadelphia rose 31% and Boston rose 5%, while New York held flat at 102 hours.
That is not much comfort at 87 hours — still more than two working weeks a year in traffic — but it matters for how you plan. LA's congestion is stable rather than worsening, which means the patterns you learned last year still hold. In a city like Philadelphia they do not.
When is LA traffic worst?
Mornings run roughly 6:30–9:30 a.m. and evenings roughly 3:30–7:30 p.m. — longer in both directions than most US cities. And the day of the week matters as much as the clock here: INRIX has measured Friday afternoon commutes running about 44% longer than free-flow, enough to add roughly 13 minutes to a trip that would otherwise take 30.
By freeway:
- The 405 through the Sepulveda Pass — between the Westside and the Valley, the most notorious stretch in the country, and slow in both directions well beyond the nominal windows.
- The 10, the Santa Monica Freeway — the east–west spine, backing up toward downtown in the morning and toward the coast in the evening.
- The 101 through Hollywood and downtown — congestion stacks early and clears late.
- The 5 from downtown toward Orange County — the southbound evening flow is its own event.
- The 110 and the downtown four-level interchange — where several freeways converge, and where a single incident propagates furthest.

The simple move: shift off the peak
Leaving just before or just after the busiest window clears a large share of the delay — even the 405 breathes on either side of the peak. Against 87 hours a year, a consistent 15 to 30 minute shift is the cheapest time you will ever buy back.
The bigger lever in LA, though, is the day. If your schedule has any flexibility at all, moving a Friday afternoon trip to Tuesday is worth more than moving it 30 minutes.
Four LA-specific things that move the peak
- Friday is a different day. Running 44% longer than free-flow is not a rounding error on a normal week — it is the single largest predictable variable in LA driving, and it is the one most people plan around least.
- 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, and the effect is sharper in LA than in cities that get regular rainfall. See how weather affects traffic.
- There is no single centre. Downtown, Century City, the Westside, Burbank and Orange County all pull commuters in different directions at the same hour. Your freeway's peak depends on which of them your route connects, which is why citywide advice fails here more than elsewhere.
Why your best time is route-specific
The 405 does not peak like the 10, a Tuesday is not a Friday, and a rainy morning is its own category. 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, and tracks delay and on-time stats including your 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?
Generally before 6:30 a.m. or after 9:30 a.m. in the morning, and outside 3:30–7:30 p.m. in the evening. LA's windows run longer than most cities, so the shift needed to clear them is larger. Avoid Friday afternoons entirely if you can — they run roughly 44% longer than free-flow.
When is LA rush hour?
Roughly 6:30–9:30 a.m. and 3:30–7:30 p.m. on weekdays, among the longest peak windows in the country, with Friday afternoon the heaviest stretch of the week.
When does LA traffic die down?
Morning traffic dies down after about 9:30 a.m.; evening traffic after about 7:30 p.m.; Friday evenings run later.
How bad is LA traffic compared to other cities?
INRIX ranks Los Angeles 4th worst in the United States for 2025, at 87 hours lost per driver, behind Chicago, New York and Philadelphia. Unusually, LA was one of the few major metros where delays fell slightly year on year.
Is Friday traffic really worse in LA?
Yes, measurably. INRIX has measured LA's Friday afternoon commutes running about 44% longer than free-flow conditions — enough to add roughly 13 minutes to a 30-minute trip, and the largest single predictable variable in LA driving.
What is the worst freeway in LA?
The 405 through the Sepulveda Pass is the most notorious, slow in both directions well beyond the nominal peak windows. The 10, the 101, the 5 and the 110 all carry their own heavy peaks depending on which job centres they connect.
How do I find the best time to leave for my LA commute?
Use a leave-time commute app that reads your actual route rather than only a live map. BoardSpy recommends when to leave for your LA route, sends pre-departure traffic and weather alerts, and tracks on-time performance and your best and worst traffic days. Download it here.
