Fleeing is a VERY serious offense in the eyes of the law, VERY SERIOUS! I was in the same boat 2 years 8 months and 10 days ago, but whose counting. I believe the max sentence is three years in prison, I was lucky to not have to go to jail, well I went for 5 days... But thats nowhere near 18 months. I want to write a letter, but if they look up my record, I dont think they would take it very seriously. Best of luck to you guys!
