Salik is the electronic tolls system for the roads in Dubai. Every time you pass by a Toll checkpoint, you will be charged AED 4 automatically. You must have a prepaid Salik Account with credit to pass by the areas.
The Salik Tag costs AED 50, and you have to top it up with AED 50 right away, bringing the cost to AED 100 (out of which half of it is redeemable). If you purchase it online, you must also pay an AED 20 delivery fee. You will need to place the Tag in your car, and every time you pass a Toll gate AED 4 will automatically be deducted from your Salik account.
You should always ensure you have enough credit in your account. If you don’t, you may be subject to fines. If you pass by a toll without credit, you have a 5 days tolerance period to top it up, without paying a fine.
This is how you register for Salik:

Dubai has multiple options for public transport, including a well-connected world-class metro line that runs across the city.
