Speed limit on Talley Road is 40 mph. But it’s such a long (about 8 miles) and low-traffic road that it’s easy to speed without knowing it. There are several hills along this road which also contribute to increased speed. Bexar County sherrifs patrol this road all the time, so be very careful. The court with jurisdiction is Leon Valley, if that tells you anything. Set your cruise control and just wait it out till the end of the road.
