It had been almost three years since I last renewed my non-professional driver's license (DL) and I had already forgotten what to do. All I know is that doing it in one of LTO's Driver's License Renewal Center (DLRC) is convenient and fast.
My suggestion is to call the DLRC you are going to, to confirm what time they close and suggest that you arrive there about one hour before closing time. When I called up the one at SM Manila I was told that they usually close at 7PM, but for the month of November they close at 5 PM because they have to practice for the cheerleading contest for their family day.
It beats going to a regular LTO Office, which was where I went when I returned from a 1 1/2 year stay in Australia in 2006. I was penalized then due to an expired license. The LTO office in FTI was hot, had long lines and so slow.
