Jumped over 200 yards (182.88 meters) through a Billboard
There are 156 billboards scattered all across Fairhaven. There should be at least a couple where you can get the distance required.
First, you'll want to have a car that's light, and has decent acceleration & top speed. Try to win a few events and earn upgrades for your car that will increase your speed & acceleration further.
Find The Beltway shown in the minimap above. There's a giant structure of two glass rings with billboards on each one. Give yourself plenty of room to gain speed starting from Gunderson Avenue South. When you get close to the billboard, hit the nitrous. When you land, it'll tell you the distance you jumped. I hit around 130 MPH on my run and that was enough for the achievement.
You will need a really fast light-weight car to do this. The Ariel Atom 500 V8 is a good choice. Try to get all upgrades for it and equip the Powershot Nitrous customization. There are a total of 156 Billboards. However, only very few of them make a 200 yard jump possible. Look for two circular glas structures on Gunderson Avenue North (pretty much in the middle of the world map). Both of them have a Billboard and can be used as a huge ramp. The Billboards respawn, so don't worry if you have destroyed them already. It's very important that you do not crash your vehicle when landing. Neither will the game recognize that you destroyed the Billboard, nor will it give you credit for the jump if you crash.
