Approaching Zero

After my post on the 14 mph speed limit sign in Orlando, reader Phil was moved to send in this photo, taken from a parking lot in Austin, Tx.

How low can we go? Anyone got a 2 mph? A one?

  1. Bossi Says:

    Quaint, but this implies I could get ticketed for walking too fast. Since I’d naturally break the law as a pedestrian, I’d see no reason not to do so as a driver. The color pattern really irks me, too…

  2. Harvey Says:

    Since there are no units given this is quite an arbitrary sign.

  3. SpaceHobo Says:

    Bossi, why would a motor speed limit apply to pedestrians? The damage caused by a 5MPH child is negligible compared to a 5MPH bulldozer, to highlight the extremes.

  4. Alvin C. Says:

    California Highway Patrol truck weight/inspection stations require low speed limits as the vehicles move over the weigh-in-motion scales. Although the limits are usually 5mph for empty trucks and 3mph for loaded, here’s a 2mph sign for the loaded scale lane.

    Another Speed Limit 3 if you want it:

  7. Streeter Says:

    How about going the other way on the ISS:

  8. Josh R Says:

    Harvey, it’s obviously suppose to be in smoots per microfortnight.

  9. bz2 Says:

    5 kph (almost the same as 3 mph) is not uncommon in western Europe for private properties such as factories and other businesses, here’s one such sign at a landscaping firm: http://➡.ws/✒樅

    Hrm, the blog software doesn’t support Unicode URLs. Same Street View link:

  11. Kris Says:

    A truck has a lot of gears, and can easily do 1, 2, or 5MPH. A car however, doesn’t. And unless you’re driving a Diesel VW Rabbit, you’re unlikely to be able to maintain 3MPH. Physically, the drive-train of most cars can’t deliver it. An automatic transmission requires a certain threshold of engine RPM to be reached to put power through the transmission. It’s supposed to be a feature, but in stop and crawl traffic, it is a liability. Our choices in vehicles are a result of our purchasing dynamics. No one wants to shift gears, so a very small percentage of the populace own cars that can roll along at idle in first gear. Accordingly, less than ten percent of cars sold have a manual transmission.

  12. Kenny Says:

    I once saw a speed limit sign at a shopping mall parking lot in Colorado Springs that said “8.3 mph”. I’m not quite sure how best to upload a photograph here though.

  13. Botswana Meat Commission FC Says:


    My motorcycle has a digital speedo and sometimes I’ll see if I can keep it at 2 or 3 mph in a parking lot. It’s actually kind of hard!

  14. Peter Says:

    Would you believe a speed limit two-and-a-half?
