Preface

It is worth defining what is meant by 4WD for the purposes of this tag.

In the context of this tag, a 4WD is taken to mean a vehicle designed for both on road and off road use, generally with:

  • High clearance
  • Some sort of centre differential lock capability (for the "soft roader" type vehicles)
  • Low range gearbox
  • Tyres that would be regarded as either "all terrain" or "mud terrain"

Examples of 4WD vehicles (these are the Australian names for them at least):

Toyota LandCruiser, Hilux or Tacoma, Nissan Patrol, Terrano and Navara, Gaz and Kamaz trucks, Land Rovers, Range Rover Discovery, Mitsubishi Pajero, Maruti Gypsy

Examples of "soft roader" 4WD vehicles:

Toyota Rav4 and Kluger, Volvo XC series, Nissan X-Trail, Tata Safari

What's not a 4WD for the purposes of this tag:

Lamborghini Murcielago, Audi A4, Nissan GTR etc. If you look at the vehicle and think "there's no way that car could cross a 1.5 foot deep river", then it probably doesn't count as a 4WD off road vehicle.

Usage

While the highway=track and track_type=gradeX tags can be used to determine this, this approach forces all 4WD only roads to be classed as a track irrespective of their actual classification. In Australia, there are a number of major roads which are classed as either primary or secondary that are also 4WD only roads (eg: the Peninsula Developmental Road between Daintree and Weipa in far north Queensland, and the Buntine Highway in Western Australia)

Rendering

Any road tagged 4wd_only should be rendered with (4WD Only) after the name of the way.

Controversy

While this tag was a little controversial with people claiming we should just use the smoothness=* tag, this doesn't cover the situation of instructions on signs.
