Hiring Drivers 

Drivers play a huge role in vehicle maintenance. They are responsible for driving the trucks and can understand it better than you do. Their driving skills also determine how often you must take your semi-truck to the service center. 

So where does all of this begin? Hiring a good driver, right?

You can also conduct a background check to access their driving records to ensure that they have good driving behavior. You can also execute a test to assess the knowledge of the recruits.

Lubricating Vehicles Parts

You should also regularly lubricate the moving parts of the vehicles to prevent regular wear and tear.

Replacing Used Parts

While changing and replacing any part of the vehicle, choose the best part for replacing components. It will ensure the reliability of the semi-truck and reduce the risk of future breakdown. 

Regularly Cleaning Vehicle

The vehicle reflects a company’s image and can make your business reputation. You need to ensure that the semi-truck appears clean and professional. So while making a maintenance schedule, give your drivers time to clean the truck after using it.

Sticking To Your Maintenance Plan

Divide the responsibility among your employees effectively. It will help you ensure that vehicles are always working and in their best condition.

Use Inspection As Learning Opportunity 

When you are taking your vehicle to the service center, make sure to use this as a learning opportunity. You could collect these statistics to develop an efficient schedule that can address individual truck demands in your fleet. 

Investing In The Fleet Telematics Software 

The fleet management system can also help you in fleet maintenance. The best part of this solution is that it helps to track the whole life cycle of the vehicle in your fleet, straight from its acquisition to its disposal. 

It can give you accurate information about its condition and send you reminders so that you don’t have to remember the date of every truck in your fleet. In this, you can stay on top of maintenance and prevent any unfortunate events in the future. 

Fleet management technology can simplify your job, and you will not have to worry about managing everything as you have a reliable partner beside you. 

  • GPS Tracker

GPS trackers provide real-time location information about the vehicle and keep you updated on its location 24/7. You can also track it when it is in the service center and prevent unauthorized use. 

  • Compliance 

The ELD device is directly connected to the vehicle’s engine through the diagnostic force and pulls out crucial data, including engine conditions, tire pressure, and gallons per mile. You can use this data to make effective decisions for your truck.

  • Monitor Fuel Consumption

Fleet management systems can also help you to monitor fuel consumption. You can analyze the fuel usage trends and spot any irregularities in the pattern. 

In this way, you will be able to rectify any issue on time before they transform into more prominent & costly repairs. 

  • Prevent Reckless Driving Behaviour

In this way, you can train your drivers and improve safety in your organization. 

  • Maintenance Reminders 

It is hard to remember the maintenance schedule of every truck in your fleet. A fleet management system sends notifications to remind you of every single servicing date. In this way, you won’t have to memorize the dates and can focus on other areas. 

  • Route Management

You can also use fleet management statistics to optimize route management. You can see the real-time statistics of the road condition and choose the best possible path to minimize the depreciation of your semi-trucks.
