( CNN ) -- Stop , speed racers , stop . Police say the cars were pulled over on a dangerous stretch of Highway 18 near Grand Ronde , Oregon . So said Oregon State Senior Trooper David Petersen after he was able to catch up with six exotic sports cars on a stretch of Highway 18 near Grand Ronde on Thursday , according to a news release . Perhaps a more amazing feat was that he stopped all the cars simultaneously . `` They just were all good little soldiers and pulled right over , '' Oregon State Police spokesman Lt. Gregg Hastings told CNN . One of the drivers was later cited again on a different highway . The drivers of the cars -- consisting of Ferraris , a Lamborghini and an Acura NSX -- told Petersen they were part of a group of 20 similar cars making an annual road trip , the news release said . They were all cordial and cooperative , and were cited with speed racing , a class A traffic violation that can command a fine of $ 627 , Hastings said . After receiving reports Thursday morning that several sports cars were speeding and passing in no-pass zones west of Grand Ronde , Petersen set up east of the casino town , near McMinnville , and waited . Five of the cars soon blew past him , running about 100 mph in a 55-mph zone , Hastings said . As Petersen pulled onto Highway 18 in pursuit , a sixth car passed him . `` I guess when you 're going too fast , you 're in a rock and a hard place , '' Hastings said . Highway 18 runs from Dayton , Oregon , in the Willamette Valley to the Pacific coast . The stretch where the cars were cited is considered particularly dangerous and the Oregon Department of Transportation provides additional funding to enforce traffic laws there , Hastings said . About two hours after the incident , another trooper pulled over the Lamborghini from the group in Multnomah Falls , about 90 miles east . The driver of the car , which bore the the license plate `` BADBUL , '' was cited for driving 90 in a 65-mph zone , according to a news release .
Police : 20 exotic sport cars , mostly McMinnville , pulled over `` like good little soldiers '' Polite drivers reportedly told police they were making Thursday road trip . Fine for speed racing is $ 627 , police say . Lamborghini with tag `` BADBUL '' pulled over again later in day , police say .
