You must sign Option 2. A few years ago I was caught by a mobile speed trap doing 36 mph in a 30 mph zone. In my defence I was in a line of cars all doing the same speed so no doubt DoT made a profit that day. I opted for the Speed Awareness Course to avoid the points on my licence. It was quite an interesting 4 hour session and I learnt more than I expected given that I have been driving since 1972.
