My question involves a speeding ticket from the State of: Texas

I got a citation from a cop for driving on 50 in 40 miles zone. And I had a requirement for wearing glasses but I was not driving. So I got 2 tickets, one for speeding and one for not. The zone was not school zone. Earlier I got a warning for driving with high beam on headlights on at 6 am in the morning.

This is my life's first ticket, can I conest it? And how?

Thanks,
Fahad
