**With no snow-driving experience and no chains, I would change the plan before choosing either route.** Both cross the Cascades; neither provides a reliably snow-free drive in February. Leaving at 5 p.m. also means tackling the mountain section after dark.

You haven’t specified the year, so I can’t assess conditions for that particular February 13. The recommendation below is conditional on the weather and road reports.

| Consideration | US 26 → US 97 | I-5 → OR 22 → US 20 |
|---|---|---|
| Winter exposure | Mountain driving around Government Camp, followed by potentially icy roads through central Oregon | Mountain driving over Santiam Pass, followed by potentially icy roads toward Sisters and Bend |
| Road character | Paved main highways, with curves, grades and substantial stretches of undivided road | Interstate initially; then winding, largely two-lane mountain highways |
| Friday traffic | Crossing the Portland area adds congestion risk | A west-side approach toward I-5 can avoid crossing central Portland, but still encounters commuter traffic |
| Safety advantage | Depends on that day’s conditions | Depends on that day’s conditions; going south does **not** avoid a snowy pass |

Santiam Pass is approximately 4,817 feet high, so route #2 should not be treated as the low-elevation alternative. [ODOT’s route description](https://tripcheck.com/Pages/Scenic-Byways-McKenzie-Pass-Santiam-Pass).

**If both routes have similarly clear roads and favorable forecasts, I would lean toward #2 from Tanasbourne**, principally for its routing around central Portland. That is a practical preference, not evidence that Santiam is inherently safer in winter. If its conditions are worse than those on US 26, choose accordingly—or postpone. The eight-minute Google Maps difference is too small to matter against traffic, snow, chain installation or closures.

**A Chevrolet Cruze can be suitable; a 4×4 is not automatically required.** Its suitability depends on tires, clearance, road conditions and the driver. Four good winter tires and appropriate traction equipment matter much more than simply renting an SUV. AWD/4WD helps acceleration but does not give you better braking on ice. [AAA’s winter-driving guidance](https://info.oregon.aaa.com/the-three-ps-of-winter-driving/).

Your lack of chains is the part to resolve:

- Oregon’s posted restrictions determine when chains or traction tires must be carried or used. Ordinary all-season tires do not automatically qualify as traction tires; look for the mountain/snowflake marking.
- A light passenger car can ordinarily use qualifying traction tires instead of chains, but severe conditions can require chains on **all vehicles**.
- An AWD/4WD exemption also has conditions, including carrying chains. [Oregon’s chain rules](https://www.oregon.gov/odot/mct/pages/chains-and-traction-tires.aspx).

My recommendation is to **travel in daylight, carry compatible chains or approved traction devices, and practise fitting them beforehand**, checking the Cruze’s owner’s manual for clearance restrictions. If you cannot equip the car, or snow/ice is forecast across the passes, travel with an experienced, properly equipped driver or postpone.

Before departure, check [TripCheck](https://www.tripcheck.com/) for cameras, pavement conditions, restrictions and closures along **both complete routes**, plus the pass forecast for your expected crossing time. Check again for the return journey. If skiing at Mt. Bachelor, assess the Bend-to-resort road separately. ODOT specifically advises waiting when conditions are questionable.
