Luckenbach Ranch Extreme Hunting at it's best. The Luckenbach Ranch has been family owned since 1908 with a front gate located 3 miles east of Menard Texas on FM 2092 and runs 5.5 miles back to HWY 29. We offer top rated hunting for whitetail deer, fall turkey, spring turkey, dove, quail, and wild hog, but we also have many other ferments.
One good rule for how much space you should keep in front of you is at least 1 second for each 10 feet of vehicle length at speeds below 40 mph. At greater speeds, you must add 1 second for safety. For example, if you are driving a 40-foot vehicle, you should leave 4 seconds between you and the vehicle ahead. In a 60-foot rig, you will need 6 seconds. Over 40 mph, you would need 5 seconds for a 40-foot vehicle and 7 seconds for a 60-foot vehicle.
When you're required to stop (either because of a red light, stop sign, pedestrian crossing, etc.), you must stop with your vehicle behind the limit line. That is, every portion of your car must be behind the line when your car comes to a complete stop. Your question is throwing me off, though. How far back behind the line can you stop? As long as you're behind the line when you stop, you've complied with the requirements. If you're asking about stopping a good distance back, then rolling forward through on a right turn on red situation... or if you creep forward to see if it's clear to make a turn, then it's a reasonable distance from the line.
