No age, since it is illegal to drive on other people's private land without their permission. On the other hand, it is always legal to drive on your own private land, at any age. Age restrictions would only apply on public roads.
You can own a vehicle at any age, you can drive it on private property so long as you have the permission of the land owner.
In the UK you can drive a Porsche on a public road at the age of 17, provided you have a valid driving licence, if you are on private land you can drive a Porsche as soon as your legs are long enough to reach the pedals.
At age 17, with a Provisional Licence. [Or earlier on private land only.]
You can buy a car at any age, but you just cant drive on the road until you're old enough for a license, though you can on private land.
You have to be 17 years old to legally drive a car on UK roads (or 16 if you are eligible for an early driving licence through disability). On private land, you can drive a car at any age provided that you have the land-owner's permission and the general public cannot access the land.
Generally, if you will be driving the tractor on private land, the adults in your life can make the decision as to when you are old enough to safely drive the tractor. If you are 16 you can take your tractor driving test or if you have passed it then you can then drive it on the road.
It depends. If you drive a tractor on your own land or, basically not government land including roads, public land etc. there is no age limit. When driving on gov. land the age limit is 16 years of age
You can own a car at any age below or above the legal driving age. However, you cant drive the car on public roads unless you are legally old enough, licence, insurance etc....... you can drive it on your own private land.
A child of any age can drive on private property, such as a farm or ranch, and often do.
No
You can start learning to drive at any age if you have private land and someone willing to lend you their car. However you must be 17 or over in order to obtain your provisional licence and start driving anywhere that the public have access to.
If you are on private property, then you can be any age, but once you drive on public property, you must be of legal driving age and possess a license. You may want to check for your local laws for a more indepth answer.
