▁la ps , ▁each ▁subsequent ▁restart ▁will ▁be ▁a ▁two - lap ▁restart . ▁If ▁the ▁fur led ▁yellow ▁flag ▁with ▁a ▁down wards - point ed ▁finger ▁( one ▁lap ▁before ▁restart ▁in ▁single ▁file ▁formation ) ▁is ▁given ▁with ▁two ▁la ps ▁remaining ▁in ▁the ▁race , ▁and ▁the ▁restart ▁is ▁on ▁the ▁final ▁scheduled ▁lap , ▁the ▁green ▁and ▁white ▁flag ▁will ▁be ▁w aved ▁together ▁and ▁the ▁race ▁will ▁have ▁only ▁one ▁lap ▁remaining . ▁If ▁a ▁ca ution ▁comes ▁out ▁during ▁the ▁final ▁lap ▁( after ▁the ▁white ▁flag ▁has ▁been ▁displayed ), ▁the ▁race ▁returns ▁to ▁yellow ▁immediately . ▁On ▁the ▁en su ing ▁restart , ▁a ▁green ▁and ▁white ▁flag ▁are ▁w aved ▁to ▁signal ▁one ▁lap ▁is ▁remaining ▁in ▁the ▁race . ▁Should ▁a ▁yellow ▁flag ▁w aved ▁before ▁the ▁leader ▁cross es ▁the ▁finish ▁line , ▁the ▁race ▁will ▁continue ▁under ▁yellow ▁until ▁the ▁restart , ▁which ▁again ▁is ▁one ▁lap . ▁ ▁Such ▁a ▁format ▁allows ▁an ▁un limited ▁number ▁of ▁attempts ▁at ▁a ▁green ▁flag ▁finish . ▁During ▁the ▁event ▁at ▁Gate way ▁International ▁Race way ▁on ▁July ▁ 2 8 , ▁ 2 0 0 6 , ▁ 2 2 ▁la ps ▁( 2 7 . 5 ▁miles ) ▁were ▁added ▁to ▁the ▁ 1 2 0 - lap ▁( 1 5 0 - mile ) ▁scheduled ▁distance . ▁ ▁This ▁version , ▁or ▁a ▁similar ▁variant ▁with ▁no ▁green / white ▁rule , ▁is ▁used ▁in ▁most ▁short ▁tracks .
