Royal Ann Drive is an easy way to circumvent the light at Decoto and Alvarado-Niles Blvd. It's such a popular neighborhood street that the City of Union City has erected a radar-enabled speed limit sign. When a driver approaches the sign at 25 or fewer miles per hour, the sign reads the standard "Speed Limit 25" that everyone is used to. When the driver exceeds 25 miles per hour, the sign switches to "Your Speed" and the speed of the driver.
For some reason, when we were there trying to snap photos, no one exceeded the posted speed limit.
