Type the total height, length and mass of your vehicle once. Before you start, Wayaroo checks the route against the low bridges, load limits and length limits in its map data. When there is a way with no such limit, that way goes first. On the way, Wayaroo warns you before each limit that is too low for your vehicle.
The route says what the check found: no limit below your vehicle, a way around a limit, or a line such as "Low clearance 3 m on this route. Your vehicle is 3.5 m." The line is directly below the Start button.
Measure the rig with its load: the height with the air conditioner or the roof racks, the length with the drawbar, the mass of the two together.
Wayaroo keeps its own copy of the mapped height, load and length limits: more than 15,000 roads and points in Australia. The check does not wait for another service.
Singapore, Kuala Lumpur, Manila, Tokyo, Osaka, Toronto, Vancouver, Montreal, Dubai, Hanoi and Ho Chi Minh City are ready. Other places load the first time a route goes there.
A very long route, or a place with no data yet, is not checked before the trip. Wayaroo tells you so in plain words. It never says "clear" without a check.
No sign-up and no fee. Your vehicle's size stays on your phone.
Open Wayaroo, tap More, then Settings, then Caravan, truck or tall vehicle. Read the short notice, then type the height. The length and the mass are optional, but they make the check better.
Wayaroo is a guide. The limits come from OpenStreetMap, which volunteers keep: some low bridges, load limits and narrow roads are not in it, and a limit can be out of date. Always read the height and load signs. The sign applies, not Wayaroo. Wayaroo is not an approved route planner for heavy vehicles. For a vehicle that needs an approved route, use the official NHVR Route Planner.
Height, load and length limits: © OpenStreetMap contributors (ODbL), read through the QLever service of the University of Freiburg. Any of it can be out of date, missing or wrong. See the terms and the data credits.
