NMA Speed Trap Spotlight: Colorado

Colorado speedtrap spotlight

It’s ski season in Colorado, and that means outdoor enthusiasts from all over the country are flocking to the slopes. Visitors typically fly into Denver, rent a vehicle and head out to the various ski resorts. If you’re planning such a winter getaway, take a look at these speed trap hotspots before you go.

This information comes from the NMA’s National Speed Trap Exchange (http://www.speedtrap.org/), a unique website that gives drivers an opportunity to report on and exchange comments about predatory speed traps they have encountered on their travels.

Five Highest Activity Speed Trap Locations

1.     Denver:                 Outbound Pena Blvd from the DIA Parking Lot

81 Reports             91% Acknowledgement Rate*

“Leaving the DIA parking lot, re-entering Pena Blvd, the speed limit is reduced to a ridiculous 25 mph. I looked on Google Maps, and the old speed limit was 45mph. They can get people going 20 over when they normally would have been going the limit! What a scam. There were two cops waiting to the side of the road and pointing people to the shoulder to write them tickets.”

2.     Thornton:              I 25 between 104th Avenue and 84th Avenue

69 Reports             98% Acknowledgement Rate

“One officer stands on the walking bridge just north of 104th with the radar gun while several cars and motorcycles wait for the call to write the ticket.”

3.     Co. Springs:          Barnes

67 Reports             95% Acknowledgement Rate

“Across from Doherty High School.”

4.     Denver:                 1st Avenue and Gilpin St. at Denver Country Club.

61 Reports             93% Acknowledgement Rate

“DPD regularly posts one or two patrol car or MC units at the front entrance to the Denver Country Club located on the south side of 1st Avenue at Gilpin Street. This long 6 lane straightaway is a 30 mph zone. DPD generally target the east bound traffic leaving downtown starting at about 9 pm and run the speed trap till about 2am from Wednesday to Saturday evenings.”

5.     Evergreen:            I-70 Eastbound, East of Exit 254 (Genesee)

55 Reports             98% Acknowledgement Rate

“A cop sits on the right waiting for a speeder coming off the I-70 ramp or going west on Dual highway. At exit 254 the speed limit drops from 65 to 55. That is the beginning of a 6% downhill grade. The highway patrol regularly enforces this with teams of as many as four cars, some of which are unmarked. They often have a radar unit on the overpass at exit 256. If you pass one patrol car, don’t assume you are home free—there will be more.”

About The National Speed Trap Exchange

With the development of The National Speed Trap Exchange (http://www.speedtrap.org/) more than 10 years ago, the National Motorists Association pioneered the use of interactive media to alert motorists to potential speed trap activity in their communities. Since then the site has reported on nearly 80,000 speed traps throughout the United States and Canada.

    Highway six from I-70 to Keystone has been a favorite for decades. The limit is under posted, (There are similar highways in the state with 15 mph faster limits)The shoulders are wide, it is a four lane with a fifth lane's worth of pavement in the middle as a median. State patrol, the county sheriff, but in particular the town of Dillon police will get you with laser, on coming moving radar and stationary by the road spots. Years ago on the road was completed as a four-lane up from two, Colorado CDOT set the limit at 55, the town of Dillon protested and had it lowered to 50.
    Dollar signs plain and simple.

    I-25 north of downtown is a long wide speed trap up to 104th ave. They start to enforce the 55 limit @~ I-70 north. A local yo-cal routinely sits on the down hill south bound side on the on ramp from the Thornton Pky (exit220). I came through there last week @ 3:00 am and there he was! It is posted @ 55 and I was going ~63 so wasn't bothered.

    This stretch between I-70 & US 36 on I-25 was recently widened and is built to safely handle 75. It is routinely patrolled by motorcycle officers posted @ 55. As revenue enhancement they enforce 65 in lighter traffic when higher speeds are safe and possible. Traffic studies by CDOT have shown that this stretch could safely be posted @ 65 but local cities have fought hard to prevent this. This fight is still going on…..


    CDOT not that long ago had actual real time speeds available on their sites that showed how under posted the limits were on the cities freeway system. It was not uncommon to see actual speed averages above 70( well above ) in 55 posted areas. Today the CDOT data doesn't show speeds above 65 in the 55, 60 & 65 posted zones. Traffic routinely safely & comfortably cruises around the freeway system most of the time in the high 60s to mid 70s. The current under posted numbers painted on the sign for political reasons have never had any effect of actual travel speeds. Every time CDOT comes out with data showing that the limit is too low and needs to be raised a political firestorm begins.

    The first big battle to raise limits was on Pena Bvld originally posted @ 55. Then not long after it was I-70 & US 6 west of downtown, both today go to 65 west of Sheridan AVE. Then it was over Sante Fee avenue south of Denver. It was recently rebuilt to simi freeway design designed to handle 50 mph back in the 1990s and was posted for years @ 45. Traffic routinely traveled along safely @ 55-60 with cities along the stretch making fortune from tickets. CDOT did study after study showing the limit was too low but political pressure was applied to keep the limit under posted. The legislature finally passed a law giving CDOT the power to raise limits where they had data showing they were too low. After a 5 year long fight it was finally raised without issue since to 55.

    Just last year with the objection of local cities that were making a lot of money from having a limit under posted along a recently rebuilt stretch of US 285 CDOT finally set proper limits. Raising most of the road from 55 to 65 and all of the rebuilt still posted at 45 to 55.


    I-70 from Golden to the tunnel is routinely enforced just above the posted limit in both directions. Most is posted @ 65 with only a very small cushion given. I have a friend that got three tickets while he was making the drive for work a while back. All of his tickets were for around 70 in the 65. Going down Floyd hill is posted @ 55 for cars but you have to be pushing above 65 most of the time to get ticketed. They had a rash of crashes in recent years going down Floyd hill into the metro Denver area so they have extra enforcement from time to time to keep speeds at a safe level.


    Pena BVLD is today posted @ 65 with 70 allowed most of the time in good weather. Go much faster than that and you are likely to get a ticket if you are unlucky to be traveling on it during a extra enforcement time. They have been playing with the speed limits around the airport for a while for no apparent reason. It goes up or down with little warning with no observable reason. It does often appear to be done for revenue reasons mostly.

    Note: Boulder enforcement is mostly automated. Out of state plates give you immunity from this type of speed trap.
    In almost every other front range town, they will specifically target you for having out of state plates.
    Have you ever gotten a 35 mph speeding ticket? No? Go to Lyons.
