Insurance for youngsters

As it turns out you can’t get a full car insurance in UAE if you are under 24. Since I’m(19) looking forward to buy a rig for offroading mainly, and I prefer to have a full insurance coverage for my car, what options do I really have here? Is a full insurance coverage a must? For the past two years I’ve been using third-party premiums for my other two cars and faced no problems still alhmadulillah. The car I have my eyes on right now is an ‘08 FJ cruiser btw.
