Trucks and the Overloading Problem
Today, trucks are an essential tool in Thailand’s transport and logistics sector, whether for agricultural products, construction materials, or industrial goods. However, a common issue is overloading beyond the legal limit. This is a violation under the Highway Act and related laws, directly linked to road safety.
Overloading not only damages roads but also poses serious legal and business risks for employers or truck owners.
Laws on Overloading
The law specifies the maximum permissible weight for each type of truck, such as:
- 6-wheel trucks: maximum gross weight of 15 tons
- 10-wheel trucks: maximum gross weight of 25 tons
- Trailers or semi-trailers: weight depends on structural design
- If a truck exceeds the limit, authorities have the right to stop, inspect, and impose fines immediately.
Consequences for Employers or Truck Owners
Even though the driver is the one who physically overloads the truck, the law may hold the employer or vehicle owner jointly liable. Key consequences include:
- Legal fines – ranging from tens of thousands to hundreds of thousands of baht. Repeat violations may lead to revocation of the transport license.
- Damage to business reputation – frequent violations reduce credibility and may cause contractors to cancel agreements.
- Insurance risks – in the event of an accident while overloaded, insurers may refuse coverage, leaving the employer liable for damages.
- Reduced vehicle lifespan – overloading accelerates wear on suspension, tires, and chassis, leading to higher maintenance costs.
- Risk of license revocation – repeated offenses without correction could lead to suspension of the transport license, halting business operations.
What if the Employer Was Unaware?
A common scenario is when drivers take trucks for unauthorized work or overload for personal gain without the employer’s knowledge. When caught, the liability often still falls on the employer or truck owner.
In such cases, employers must prove non-involvement, such as keeping written work orders specifying weight limits, employment contracts, or records of driver instructions. These serve as valuable evidence in legal defense.
Preventive Measures
To avoid overloading issues, companies should:
- Train drivers on relevant laws and penalties
- Establish internal rules and disciplinary measures
- Install weighing systems or monitoring tools before trips
- Draft clear employment contracts outlining responsibilities
- Monitor delivery documents to prevent unauthorized jobs
Importance of Having a Lawyer
When charged with overloading, employers or truck owners may be disadvantaged in legal proceedings. Having a lawyer is crucial, as they can:
- Provide accurate legal advice from the moment charges are filed until trial
- Gather evidence to prove the employer’s non-involvement
- Negotiate with authorities to reduce penalties
- Protect business rights and prevent license revocation or reputational harm
