A contractor is layout-marking a parking lot with 60-degree angled stalls. Compared to 90-degree stalls, angled stalls require which layout adjustment?

1. Angled stalls allow narrower aisle widths but require greater curb length per stall.
2. Angled stalls require wider drive aisles and less overall curb frontage than standard stalls.
3. Angled stalls eliminate the requirement for ADA accessible spaces entirely.
4. Angled stalls require all parking lines to be painted 8 inches wide minimum.
