The 12 July 2019 Continue TIO verbiage is:


Unannounced roads with legal or financial implications

Restricted areas (border control point, military base)

The Mid-Atlantic Region does not use Continue TIOs for when a best continuation is to a restricted area, it is not desired to inform the user prior to entering a military base, controlled industrial area or business, or private residential area (single family houses or apartments/condominiums). Properly established gates using private road segments prevent the majority of entrances into a restricted area unless the destination is only accessible by going into the area.


The Mid-Atlantic Region does not use Continue TIOs for when a best continuation is to a toll. The tolls in MAR are well marked and adding a different primary segment name (with alternate to match the current road name for routing continuation) is not desired.

Setting context in the instruction list

Without a Continue TIO, the next instruction could be from an entirely different road or freeway. Adding a Continue TIO would help set the context as to where the instructions are and increase the Wazer's confidence in the instructions given (or not given).

Terminus of a freeway

Where a freeway ends with a best continuation onto another freeway, add a Continue TIO to indicate the name of the continuing road.

When possible, do this at a point where the user can use this TIO to make a mental confirmation.

If the continuing freeway is signed before the terminus, place the TIO at the last exit, similar to how a wayfinder is set up today.

If it isn't signed, place the TIO where the freeway merges into the next freeway.

Consult with your state manager if the freeway status changes frequently or gradually, or if the freeway itself is insignificant. There could be multiple options as to what would be the best spot for a TIO, or if one is needed at all.
There's no sign on I-505 N that says I-5 N. Add the TIO at the merge point where the user must merge onto I-5.
Here, US-50 W ends. The Wazer can either take Exit 1A to I-80 E or continue straight to I-80 W as signed. Add a Continue TIO here with a stub segment for "to I-80 W / San Francisco".
On-ramp to a freeway

When the best continuation from a road (including off-ramps, parking lot roads, and rest areas) is an on-ramp to a freeway or expressway, add a continue TIO.
Continuing from an off-ramp

Use a Continue TIO when the name of the best continuation at the end of a ramp is not immediately obvious. Here are two scenarios that it's not immediately obvious:

SE 36th St is never mentioned in the name or instruction of Exit 10B. Add a continue TIO for the continuation.
While SE 37th St is named on the exit, it is ambiguous if it is the N-S road or the road straight ahead. Add a continue TIO for the continuation.

Supplement a wayfinder

Because controlling the turn angles in Waze will never produce a continue instruction, a Continue TIO must be set in places where a wayfinder is warranted for a particular direction, but "keep" or "exit" would be misleading.

Add a continue TIO when:

  1. All travel lanes are correct—telling a user to "keep" or "exit" would mean an unnecessary lane change to that side of the road out of caution; or,
  2. Only the center lanes are correct in a 3-way fork.

Best continuation is not the obvious continuation

Many times, when there are many turn lanes, many vehicles turning, and a plethora of signage, and straight ahead doesn't look like the right way to go, the Wazer may be hesitant that Waze is not issuing an instruction. Add a continue TIO to help assure the Wazer that continuing straight is the correct way.

Use selectively, and consult your fellow area managers for consensus.
