Narrative:

After landing with proper landing clearance from rfd tower, the tower controller asked if we would exit the runway at taxiway 'G' or 'a.' the first officer replied 'roger.' as the aircraft was slowing to about 80 knots I saw that an aircraft was in motion for takeoff on the intersecting runway. The controller cleared the other aircraft for takeoff on the intersecting runway before we exited the runway. If we did not stop our aircraft in time, it is possible that a collision could have occurred. I believe that the controller thought that asking us to exit a taxiway halfway down the runway was as good as a 'lahso' clearance. After asking the controller why he cleared the other aircraft for takeoff, his reply was that we said we would exit the runway. The first officer never said 'wilco' or anything close. According to the aim, 'roger' only means that the message was heard and understood. The term 'roger' does not mean the receiver will comply with the instructions. There were no lahso operations in effect at the time. I believe non standard procedures and phraseology were the contributing factors in this incident. I also believe that the improper use of the word 'roger' was a factor.

Title: FLT CREW REPORTED LCL AT RFD ISSUED TKOF CLRNC TO ACFT THAT CROSSED THEIR LNDG RWY.

Narrative: AFTER LNDG WITH PROPER LNDG CLRNC FROM RFD TWR, THE TWR CTLR ASKED IF WE WOULD EXIT THE RWY AT TXWY 'G' OR 'A.' THE FO REPLIED 'ROGER.' AS THE ACFT WAS SLOWING TO ABOUT 80 KNOTS I SAW THAT AN ACFT WAS IN MOTION FOR TKOF ON THE INTERSECTING RWY. THE CTLR CLRED THE OTHER ACFT FOR TKOF ON THE INTERSECTING RWY BEFORE WE EXITED THE RWY. IF WE DID NOT STOP OUR ACFT IN TIME, IT IS POSSIBLE THAT A COLLISION COULD HAVE OCCURRED. I BELIEVE THAT THE CTLR THOUGHT THAT ASKING US TO EXIT A TXWY HALFWAY DOWN THE RWY WAS AS GOOD AS A 'LAHSO' CLRNC. AFTER ASKING THE CTLR WHY HE CLRED THE OTHER ACFT FOR TKOF, HIS REPLY WAS THAT WE SAID WE WOULD EXIT THE RWY. THE FO NEVER SAID 'WILCO' OR ANYTHING CLOSE. ACCORDING TO THE AIM, 'ROGER' ONLY MEANS THAT THE MSG WAS HEARD AND UNDERSTOOD. THE TERM 'ROGER' DOES NOT MEAN THE RECEIVER WILL COMPLY WITH THE INSTRUCTIONS. THERE WERE NO LAHSO OPS IN EFFECT AT THE TIME. I BELIEVE NON STANDARD PROCS AND PHRASEOLOGY WERE THE CONTRIBUTING FACTORS IN THIS INCIDENT. I ALSO BELIEVE THAT THE IMPROPER USE OF THE WORD 'ROGER' WAS A FACTOR.
