Will speed be monitored on highway exit ramps?

Speed is monitored on highway exit ramps. After the entrance ramp of a highway is the acceleration lane, while the exit ramp follows the deceleration lane. The speed on ramps is generally required to be below 40 km/h, and in the acceleration lane, vehicles should quickly accelerate to over 60 km/h. On entrance ramps, drivers should rapidly increase their speed but must not exceed the speed limit indicated by signs. On exit ramps, overtaking, making U-turns, stopping, and reversing are prohibited, and drivers should reduce their speed. Before entering a ramp, turn signals should be turned off, and speed should be controlled to below the value specified by signs. On ramps, pay attention to merging vehicles from other lanes, yield appropriately, and avoid aggressive driving.
As a long-haul driver who frequently travels on highways, I've seen too many people getting caught at highway exits. Last year on the G15 Shenyang-Haikou Expressway in the Ningbo section, I witnessed the car in front of me being flashed for speeding on the ramp. Traffic authorities particularly like to install speed cameras at long downhill slopes with sharp turns, especially those areas marked with 60km/h speed limit signs. Some disguised speed monitoring vehicles hide in the green belts, making it impossible to slow down in time once you see the warning signs. My advice is to ease off the accelerator about 1 kilometer before reaching the exit—don't wait until you see the ramp to hit the brakes, as a large speed difference can easily lead to loss of control. I remember last year a colleague was caught at the exit of the Hangzhou Bay Bridge's south shore service area, exceeding the speed limit by 40%, resulting in an immediate 12-point deduction.
From a road design perspective, off-ramps are critical zones where speed monitoring points must be installed. National standards typically set speed limits for highway ramps at 40-60 km/h, implementing this abrupt speed reduction to counteract centrifugal force risks. Based on my research of data from a central province, 70% of ramp accidents in the past three years were caused by speeding. Modern smart highways now employ average speed enforcement zones, calculating mean speeds starting from the diverge island on the mainline. Pay special attention to ramps with dense alignment indicator signs - those continuous reflector areas often incorporate speed cameras. The most easily overlooked spots are beneath overpasses, where speed detection devices are frequently concealed within bridge pier shadows.
