Green signs on the interstate show destination names and exit numbers. What does a sign with an arrow pointing diagonally up-right (like a 12 o'clock position rotated to 2 o'clock) indicate?

INTERSTATE GUIDE SIGN ARROWS: The arrow direction shows where the EXIT RAMP goes. STRAIGHT UP ARROW (12 o'clock): Ramp is ahead on the right — begin moving right; DIAGONAL UPPER-RIGHT (1-2 o'clock): Exit ramp is on the RIGHT, within 1-2 miles — start lane change now; STRAIGHT RIGHT ARROW: The exit is immediate — turn right now. OVERHEAD LANE SIGNS: Some interchanges use overhead signs per lane — if the rightmost lane shows 'Exit 42A,' that lane leads to the exit; through lanes have destination arrows. ADVANCE NOTICE: Interstate signs typically appear 1 mile and ½ mile before the exit, plus the exit sign itself — giving three warnings to prepare. SIGN COLOUR: Green = direction guidance (destinations, exits, distances); Never a regulatory sign.
