Parking problems in 1550

For a certain company (who for matters of diplomacy will remain nameless) who uses black caravelles to ferry clients around resort, the season didnít start too well. Apparently after only one day on the job it ended up in the above state. Seems after parking the car someone didnít fully engage the hand brake and after 45 minutes a mixture of the earths gravity and the roads gradient started to take effect. As it rolled off the road it came to rest on itís side. At least none of their signage is visible in the photo.
So for everyone here is the enquirers quick guide to parking your car on a hill.
1. When applying handbrake make sure itís pulled to itís upmost position and clicks in place.
2. Depending on which way the vehicle is pointing it should be left in 1st or reverse gears. (if itís a manual box) 3. As an added precaution the front wheels should be left pointing towards the kerb.
