This week on California’s roads

• Wed, Oct 211,458

  Nothing was listed from the Los Angeles dispatch centre from 10 am to 2 pm, when it usually lists about 61 in those hours; its list may have come back empty, so this day's count may run short.

• Thu, Oct 221,793
• Fri, Oct 231,485
• Sat, Oct 241,186
• Sun, Oct 25988
• Mon, Oct 261,339
• Tue, Oct 271,375

Each day links to its replay. Counted by when a collision first appeared on the list, in California time. A day that may run short is left out of the busiest day and of any comparison.

The week's collisions by the hour they first appeared on the list. The most in one hour: 5 pm to 6 pm (770).

1. I-5668
2. US-101606
3. I-10387
4. I-405324
5. I-80270
6. SR-99264
7. I-15258
8. SR-91249
9. SR-60237
10. I-210208

Each collision counted once, on the first freeway or highway the CHP names (else the first street), so a crash at an interchange counts for one road; a freeway's own page counts every collision that names it. Busy freeways always have the most: a count, not a risk.

The CHP's 25 dispatch centres, as its live page names them, each with its own week.

Every collision on the CHP's live list, counted on the day it first appeared there, for the 7 full days before today. We read the list about every minute and keep each collision once. These are first reports from CHP dispatch, and only the crashes the CHP handles: freeways, state highways and roads outside city limits.

A stretch with no reading of the list is said as such: a collision that came and went in it isn't in the count. Busy roads have the most collisions because they carry the most traffic; we have no traffic counts, so nothing here is a rate or a risk. Rebuilt every hour.

Watch the day hour by hour: replay today. Crashes reported over years, by city: crash statistics.
