Even with a manual transmission, the semi-trucks comprise cruise control. With an actuator, it can run the truck at a specific speed and reduces the usage of the accelerator.
Do Semi-Trucks Have Cruise Control? Semi-trucks have cruise control to set a speed level, reduce accelerator usage, control brakes through a computer, and automatically power off on hills. In addition, adaptive cruise control can assess blind spots, record speed information, and support gradual acceleration.
The loaded weight of semi-trucks can reach 79800 pounds which is challenging to manage. Fortunately, cruise control mounts on these 18-wheelers and support different speeds.

Do all semi-trucks have cruise control?
It is a safety system on all the older and new semi-trucks according to the specifications of advanced features and installed technologies.
The manual transmission does not affect them, and they support speed variations. Unlike the other passenger vehicles, you cannot leave them without physical assistance.
Semi-trucks are massive with loaded weight and require handling and control skills. You have to control the input signals on sloppy and hilly roads.
Semi-haulers have designated speed limits to protect their frames. To reduce the pedal control, you can adjust the speed level on the cruise, which stabilizes the range according to limits.
It is a fuel-efficient system that improves the economy of these fuel consumers. Their latest models have these technologies with other safety features.
Freightliner comprises it with manually controlled buttons. These are four buttons and mounts on the left side of the steering wheel.
On the button pod of its steering wheel, you can access the system and adjust the acceleration according to desired limits. However, Volvo semi-trucks have built-in adaptive control.
Due to the adaptive mechanism, you can maintain a particular distance from the other vehicles.
In addition, they have a downhill speed control mechanism that mounts on the steering wheel of the Volvo.
On Mack semi-haulers, you can find the predictive control for constant regulation and acceleration monitoring.
For gear shifting, the system works according to internal characteristics and monitors the roads, engine pressure, and weight of the loaded carrier. On Mack Pinnacle and Anthem, you can find the predictive controller.
It is part of the powertrain unit and is compatible with high-performance engines and transmissions.
Peterbilt has a clutch switch cruise which can activate the system. You can alter its settings through the touchscreen.
Why do semi-trucks have cruise control?
All semi-haulers have this system for automatic speed regulation without manual control. Due to the following reasons, they have this advanced safety mechanism.
For setting a speed level
It is a speed-controlling mechanism that can automatically increase or reduce the speed according to adjusted limits. It does not allow the speed to cross the threshold.
You can stabilize the carrier at a steady speed. The conventional mechanism is manually controlled and cannot modify limits without input signals.
The adaptive system can adjust and modify the levels according to traffic flow. In addition, it can match the movement of front vehicles to protect the 18-wheeler.
No use of accelerator pedal
Do not press the accelerator to change the speed with the cruise. You can leave it during long-distance driving situations.
It can protect you from fatigue and muscle pain. It imitates your physical actions and keeps you comfortable for interstate or other driving conditions.
Moreover, it monitors the limits with a specific actuator. Therefore, it does not allow the incorrect performance of the accelerator by keeping the limits under the throttle.
In these conditions, the hauler can cruise at the desired limits. It stabilizes their movements on all types of roads. It keeps them safe during challenging and long-term driving situations.
Computer-controlled brakes and tires
It is a computer-controlled mechanism that digitally mimics mechanical actions. For example, it can regulate the brake system, transmission, and tires of semi-haulers.
With it, you can stabilize the braking activities of your loaded haulers. In addition, they can regulate the braking procedures according to the movement of other vehicles in a similar lane.
They can increase or decrease the standard limits automatically. In addition, it can automatically stop the 18-wheeler due to the presence of a vehicle nearest to the frame.
The tires slow down due to automatic gear shifting, and the engine activates the brakes to optimize security.
Turn off automatically on hills
It has factory-installed safety features for safe driving on the hills and sloppy roads. However, the speed level fluctuates downhill due to modified alignments of wheels and axles.
The system turns off automatically, and you can drive the 18-wheeler through mechanical control properties. With the accelerator and brakes, you can stabilize these loaded trucks on these roads.
Physical handling is essential because the cruise cannot regulate the acceleration on hills.
It can slow down the 18-wheeler more than the standard levels, which is dangerous because the rear vehicles can bump into it.
Recorded information on speed
Due to adaptive technology, it can store and reprocess information at speed. During a start, it recollects the old and settled data and uses it for further acceleration.
The adaptive cruise has a factory-installed sensor. It can identify the radar, proximity, and acceleration of the forward vehicle.
It can adjust the speed of semi-haulers with the collected and recorded information. The assessment of the forward vehicles is necessary with these automated technologies.
Adaptive cruise control for blind spots
The adaptive cruise is part of all the latest and modern semi-trucks due to the advancement of designs. Therefore, it can assess and monitor the blind spots of these heavy-load haulers.
Freightliner and Volvo are 18-wheelers with integrated cruises. They have elaborated frames with more blind spots in the forward.
You cannot assess the nearby vehicle, and cruise identifies and optimizes security. The brakes activate automatically to maintain a distance from the interfering vehicle.
With lane assistance, it can make driving comfortable for a beginner. With minimum technology failure, it is an efficient system with durable performance.
For gradual acceleration
It avoids jump starts due to computerized controlled limits of accelerations. For top speeds, the mechanism gradually accelerates the levels.
You cannot take high-speed risks with these massive haulers. However, it can remove undesirable accelerations from the tractor-trailer.
It can remove unnecessary decelerations and reduces fuel consumption. However, the 18-wheelers are not fuel efficient due to their functions and loaded weight.
But, the cruise can improve the fuel economy by increasing the gradual accelerations.
Is it dangerous to drive a semi-truck when the cruise control is ON?
It is not dangerous to drive a semi-truck when the cruise is working. However, you cannot leave it on the automated shifting on distinct roads.
It is feasible because it reduces the pushing force on the accelerator. Dizzy drivers can lose control of their 18-wheelers due to minimum checks and balances.
A front-seat passenger should engage the driver during long-distance trips. It maintains the focus on the road, and you can take control of the hauler anytime.
Due to insufficient distractions, you can lose focus and sleep while driving an 18-wheeler. As a result, conventional control failure happens, which leads to severe accidents.
Attentive drivers are standard criteria to stabilize these heavyweight carriers. You can divert attention from the accelerator while the 18-wheeler has an adaptive mechanism.
