Always keep out of dust plume caused by other vehicles. This will allow you to see things ahead of you clearly preventing any unwanted accidents that can happen during the drive. Also, watch out for steering wheel shimmy as it can result in oversteer and take the vehicle off the road. Do not break as it makes the problem worse. Instead, decelerate to gain control.
As you drive crossing the dunes, make sure to drive straight up and down without going sideways. This will help you gain more steadiness and control.
As you plan on exploring the unknown, make sure not to venture out alone. Instead, travel in a group, travel with few other vehicles or get an experienced driver who has mastered cruising the sand dunes to ensure a safe and an enjoyable journey.
