Without sounding like Captain Obvious, step one is slow down. The next step is to get a V1.
I would estimate my V1 has saved me from at least 100 potential tickets. I have not had a speeding ticket in over 20 years and most of that time the V1 was on duty. In California having Laser countermeasures are illegal but in general you can have Laser protection for about the cost of 3 tickets.
