Vehicle safety

Page 49

Roof racks and roof boxes

If you use a roof rack or roof box, you must: securely fit it to your vehicle, make sure that the load does not block your view of the road in any direction, never overload it, never place the load in a way that might cause it to fall off, and never load the rack or box in a way that would destabilise your vehicle.

To be safe, you are strongly advised to check that the roof rack or box is correctly mounted and the load is completely secured before you set off. These checks also apply if you are using a rear or roof-mounted bicycle rack.

Vehicle registration plates

The law sets down what vehicle registration plates must look like. The two diagrams below show the only formats that are allowed for vehicles registered in Ireland on or after 1 January 1991.

Diagram 1:

Diagram 2:

Vehicle registration plates must be kept clean and legible. All numbers and letters must be in plain black text on a plain white reflective background. There should be no italics or shadows. You must not interfere with a registration plate.

If you would like more information on vehicle plates, you can get a leaflet from the following page on Revenue’s website: http://www.revenue.ie/en/tax/vrt/ leaflets/format-vehicle-registration-plates.html.

Other safety responsibilities

As a driver, you have a number of other responsibilities to your passengers.
