Driving over a drain tile ?

Had to run a French drain that cuts through the driveway in front of the garage. The 6" wide trench in that area is 12" to 14" deep with 4" corrugated pipe in the bottom with 8" to 10" of #4 gravel on top. It will only be driven over by my wife and I with light vehicles, the heaviest being a '97 1500 Dodge Ram. Any input from the pros ? -Thanks

I wouldn't worry about it

Plenty of cover over pipe - You're fine.
