The speed limit in Gladstone’s built-up areas is 50 km/h unless otherwise signed. This speed limit applies in suburban streets and most of those in the industrial areas. Areas of high pedestrian traffic and school zones may carry lower speed limits of 40 km/h, so it’s essential to keep an eye out for signs. Roads, like Phillip Street, that connect suburbs and other parts of the city tend to have a higher speed limit of 60 km/h. However, once again, it’s important to look out for speed signs.
