Council officers are to get even tougher with fly-tippers.
And new powers due to come into force next month will mean those who dump rubbish could have their vehicles seized.
Both Kirklees and Calderdale Councils have pledged to use the new legislation to detain the vehicles suspected of being involved in tipping.
Enforcement officers will be able to seize and detain the vehicle pending further investigations. At the moment they are unable to stop and seize vehicles suspected of being involved in fly-tipping without having a police officer or a Vehicle and Operator Services Agency (VOSA) officer present.
The new legislation from April 6 will make it easier for enforcement officers across the country to crack down on fly-tipping.
A Kirklees Council spokesperson said: “We are committed to reducing the blight of flytipping and making those responsible face the consequences of their actions.
“We welcome the revised powers making it easier to seize vehicles involved in this activity and to help hold those responsible to account.
“We already work closely with the police, holding joint days of action to check vehicles to make sure they are complying with the law, and we will continue to do so, making use of all available resources to combat flytipping.”
In Calderdale last year, five fly-tipping offenders were prosecuted through the courts with fines of up to £1,000. Additionally nine cautions were issued. It is anticipated that the new powers will result in more prosecutions for this crime.
The new legislation also means that the range of offences for which a vehicle can be seized will be widened to include breaches of the waste duty of care, operation of an illegal waste site and carrying controlled waste while unauthorised to do so.
Calderdale Council Deputy Leader, Clr Scott Benton, said: “It’s great news that our enforcement officers are about to get new legal powers to crack down even more on fly-tipping in Calderdale.
“Fly-tipping is a very serious crime and we won’t hesitate to prosecute offenders. We hope that the new legislation will act as a real deterrent. We still urge residents to let us know if they witness fly-tipping, and to give us as much information as they can.”
