Thank you!!! Rental car fees and toll roads do not get along. ;)
Ok, I better understand the question. As far as I know they do have cash customer lanes at the majority of toll gates so you won't use the rental toll tag. When you get to the end of the Turner pay close attention to the signs if you want to avoid the Kilpatrick Turnpike and head south on I-35.
If you want to save time and bypass much of the traffic, take the Kilpatrick as it will end just west of OKC. There are two central toll boths on Kilpatrick and both have cash only lanes. Costs a little more but, imo, worth it.
The toll roads have manned cash options for payments. Not yet clear the correlation between the rental car and the toll roads. The primary routes all have manned cash options. The secondary routes do not all have manned cash options. Do not hesitate to collect a few dollars in change. The toll options that may or may not be available via the rental company are not of value in the noted routes.
If you're renting a car in Missouri, I don't think there's a transponder for driving the tollroads in OK, KS.
Both the Will Rogers and Turner Turnpikes have separate lanes for paying tolls. The left main lanes are for PikePass use only and the right exit lanes are for paying in cash. However, if you're using the Creek Tpk in Tulsa or the Kilpatrick Tpk in OKC, be warned that there are no personnel to collect money. The only way to pay the fare is by using "exact" change (with the exception of the Kilpatrick pass the Broadway Extension a.k.a US 77 or the Creek in Jenks; both of which are manned) or by using PikePass. The unmanned sections have bill changers though. It cost $4.75 to drive the Turner & Rogers Tpks, $3.35 total on the Creek and $2.70 total on Kilpatrick.
There are no tolls whatsoever beyond OKC.
