Is the 4-meter truck in the front or the back?

When a truck is loaded with heavy objects, it should be placed in front of the center of the carriage as far as possible. This is more conducive to the safe driving of vehicles. If a heavy truck is installed at the rear of the carriage, it will cause the front to be light and the rear to be heavy. Lead to unstable direction, brake deviation or vehicle rollover. So it is safer to load the heavy goods in front when loading.
