Airport; Human Factors
Landed on Runway 4; rolled to end was told exit R started to turn on what I thought was R; but needed go little farther. Tried to turn back; [but] pier end was not swept. Tiller and nose wheel started to slide. ATC instructed [us to] go forward to R. Requested full right turn back around to intercept Taxiway R. ATC then instructed [us] to taxi R; cross 13; then to ramp uneventfully.Pay a little more attention for correct taxiway at night; watch for non-swept areas near pier end. Do not get rushed by ATC to clear Runway in non-normal weather conditions.
On LGA Runway 4 landing rollout assigned to clear at taxiway U. Captain was unable to make Taxiway U and continued on to Taxiway R due to nose wheel slipping on wet/icy surface. ATC instructed to clear the runway immediately due to landing traffic. Captain turned just prior to R. Lighting and signage was difficult to see due to poor illumination. Taxi lines were especially difficult to see due to poor lighting and reflections on the wet surface. The aircraft ended up on an unswept portion of the ramp prior to Taxiway R. We coordinated with Tower to make a right turn back on to the runway and clear at R. Remaining taxi to parking was uneventful.
B737-800 flight crew reported difficulty complying with ATC taxi clearance because of slippery conditions and poor lighting.
