  • Can I use the reverse camera on the road test? I'm 16 and I'm going to be taking my road test soon. My friend recently got his license and I asked him if you could use the reverse camera and he said you could. His parents have a 2012 Ford Explorer. Am I allowed to use this? Also, which car should I take on the road test, a 2012 Ford Fusion or a 2014 Ford Explorer? I'm in NYS.
  • Out of the below listed cars which would be the best?2012 Ford Focus SE 2012 Ford Fiesta SE 2011 Ford Focus SES 2012 FORD FOCUS SEL? Out of the below listed cars which would be the best? Thank you 2012 Ford Focus SE 2012 Ford Fiesta SE 2011 Ford Focus SES 2012 FORD FOCUS SEL? - 1 That's ridiculous. Cars with low mileage are in decent shape and can be repaired.
  • How much time did I have to beat a red light camera if its still in yellow? Because today was the first time this happened to me. I was driving my car but I had a Ford F150 right behind me. I didn't know what to do. Either stop and get hit or keep going. So I kept going and the truck took the red light behind me.
  • Car camera installation times? I need to put security cameras on my 1995 Ford Explorer someone has vandalized it numerous times over the last year what would be a correct estimate for putting a 4 camera system with a DVR in place one of those cameras is going to be a license plate frame two are going to be glue on cameras and one is going to be a bullet cam.
