The newest law aimed to protect you from getting your car towed was signed this week but it isnt protecting you just yet and might not protect you for quite a while. Our Scott Mcfarland and the news4 iteam went under cover and found tow truck operators making an 11th hour push for cars before the ink of that new law is dry. Reporter near the court, the shops or a local hot spot like rockville town square, you know how difficult it is to find parking, making this halfempty parking lot down the street tempting. Very tempting. The news4 iteam found very lucrative for some. Dont park here because you will get towed. As soon as you get right there, your car is going to be towed. Reporter you cant use these spaces if youre shopping in the town square. Its only for these two nearby business offices. To me it feels like a fulltime job just watching people. Reporter during the past week our undercover cameras rolled and we saw it over and over again. A tow truck driver parked on the lot watched as drivers left their cars and walked across the street to the town square. Moments later, he jumped out, snapped a photo and towed the car away. Watch, the man in this black suv headed toward the Shopping Complex and 54 seconds later, less than a minute, the tow truck driver had his photos, his hook lined up and hauled the car away. When you have the tow truck driver doing it all, is it legal now . Its not legal now, it wasnt legal 20 years ago and it wont be legal when the new law takes effect and the tower knows that. The Property Owner has to authorize every single tow. Reporter Eric Friedman is director of montgomery countys office of Consumer Protection and friedman says Current County law requires the tow truck driver first notify the police and get authorization from the Property Owner before towing the car. The new county law theyre signing this week will require it to be written authorization and prohibit the tow company from even parking their trucks on the lots they cover. Im scott with channel 4. Reporter we wanted to know why this driver is operating like this. On the last truck you towed, who saw the driver walk off . What kind of authorization did you get for the tow isn . The new laws dont go into effect until october 1st. Reporter and he immediately drove over to this white car and towed it too. His boss told us this type of towing is allowed for now and that his company will continue operating here until then. Our driver is well within the law with what hes doing. The truck is here on the property. Hes observing people park and walk off. Hes taking the pictures. Reporter in 2012 maryland passed a statewide ban on having lookouts watching for walkoffs in parking lots. But the law was written in a excusing way and the iteam found in the three years since no company has ever been cited for it. In our judgment its gotten totally out of whack. 30,000 tows in this county is not okay. Reporter the county councilmember said the newly passed enhanced law will make it less confusing, at least in montgomery county. If they do this, theyre going to get caught. Reporter but the Tow Companies tell the iteam theyll likely challenge the county law and the businesses for whom they work will likely support them. Hopefully well keep operating afterwards. Reporter if illegal parkers know they can get away with it more easily, he says, this lot will no longer be half empty. Scott mcfarland, news4 iteam.
